• Weistec Engineering now offering Stage I Naturally Aspirated M156/63 AMG tune - +47 wheel horsepower on 91 octane, $990

      We thought this eventually might come but not so soon. Weistec has decided to sell a naturally aspirated tune for the M156 V8 which offers gains of 47 wheel horsepower on 91 octane, impressive. In addition to the horsepower gain torque is upped by 32 wheel, the speed limiter is removed, and the throttle response is optimized. The price is a very reasonable $990 which also is credited toward a supercharger purchase should one decide they want more power.




      Key Features:

      • +47 Wheel Horsepower
      • +32 Wheel Torque
      • Eliminate Top Speed Limiter
      • Increased Throttle Response
      • Optimized Fuel and Spark
      • Credit towards Stage 1/1+ Supercharger Systems


      To order: http://weistec.com/m156nas1.html

        One way, in my opinion, is to just list it in the first post. You don't have to, but I think it would be clearer and much harder to miss, and would most definitely help the tuner as well. The more information the better for everyone.

        Another way to look at this is as showing tremendous interest in the product and bumping the discussion essentially created further interest. I do not see any negatives and simply a respectful discussion including clarifications that were necessary. So don't worry Mo, I don't think anything you or I stated has detracted in any way and if anything only fueled further interest. It's all good Click here to enlarge
        I just feel bad their thread may have gotten polluted by too many off topic issues and took away from the focus on the product itself. I doubt someone interested in the tune would sit and read 7 or 8 pages of back and forth from different parties about different things Click here to enlarge

        Well nobody said 47 tune only other than you so I just don't see how it is relevant. I mean +13834 whp tune only isn't happening but it is rather pointless to point it out as it doesn't apply to the topic. Regardless, we'll see more results soon that should hopefully put this all in better context.

        I didn't skim over your point as I responded to it and stated it was with filters? We're talking page 2 page 28 and the beginning of the thread where I said it reminding of what was already there not page 7.

        Posting the graph is listing it in the first post. You mean additional text in addition to the graph? At what point does this become redundant and when do we just expect people to look over what is already provided? It's all clear and it's all there. I can't assume what will sink in or what won't.

        I think this goes to show how short our attention spans have gotten. I don't know if more text is the answer to that as I keep things concise as is and yet people still miss big points. The graph is the main piece of evidence and where eyes should be focused to see the resutls, the text is a supplement.

        I don't think most people are reading this entire thread through but likely focusing on the OP and the announcement. So, if they aren't reading it as you likely correctly surmised I do not believe it is taking away from anything. Also, it is likely getting more people to view the OP. So don't worry about it, some discussions will go a little OT no worries!

        Man I would love this, but I would really like a PnP option, since this car will be my only car and I'm not in the Weistec area... Click here to enlarge I would love to be able to get it, seeing as I do 93 readily available in NC...damn...jealous...I might have to take a long trip there sometime...

        Relevant to the E63 and CLS63 platform as tune only gains with that proportions would indicate the tuner did really accomplish things other tuners have not.

        Agreed. And I honestly look forward to Weistec's progress as they advance the platform forward.

        I was just talking about my first post for which you didn't say anything for 2.5 hours and a few back and forth.

        I think it would only add a professional touch (not repetitive) to list a brief description of what Stage 1 consists of in a nicely organized manner, and also give a graph. Providing one thing or the other is definitely good enough, but I think it would be better having both. Many of the big name companies follow that strategy.

        I know it's an inconvinience, but you can always try to minimize the down time.... maybe send the ECU on a Friday and have Weistec overnight it on Monday. 93 octane would see even better gains Click here to enlarge

        Hmm...that would be nice...never even thought about upgrading my tune though. What do I have to think about with a flash tune? Like if I take it into a MB dealer for work? Things I should think about before I get it done...

        Why wouldn't you be able to get it? I don't think you have to be local.

        Perhaps but that is not what is the question here or the topic. It's like saying I am right that you can't gain 1080808 hp tune only, it isn't applicable or relevant. What happened here with this specific tune on the E63 is what is shown in the OP.

        Mo this originated with you saying toward the end of the thread you were surprised I did not mention the filters yet clearly I did. 2.5 hours later or whenever really I did mention it so you were incorrect in saying I did not and secondly operated under the assumption for a long time that this was tune only despite two posts from me stating otherwise including the very first post. It isn't a big deal I'm just glad it's cleared up.

        Well that is your opinion and that is fine but I think the graph and details provided answer any questions as the information is all there. All one has to do is simply look at the graph. I'm not going to start second guessing what people take away from graphs as then I will have to spend much more time writing everything that is alreadly plainly visible in the graph such as the changes across the curve, air fuel, peak gain, etc., when it is all already there. I don't think I need to take time to for example spell out where the hp and torque crosses when you can see it (and is always the same anyway). In my opinion that would be redundant and take up way more time than necessary as I think posters are intelligent enough to be able to look at things and retain information. I do not need to spell every single thing out.

        Any other questions can be fleshed out in the discussion.

        Difference of opinion I suppose but anything you needed was already there so all the information was clearly and concisely provided which I believe is the professional approach.

        Glad to see someone else in a futile and annoy debate with Joe. Is that what it looks like? Sheeshh.. When I said talking to a wall I think I was being nice. Its more like... Click here to enlarge

        Moe, you know Joe. Admit he is right or just let it go. No point otherwise. I believe you and I are on the same page.


        Joe, I understand where you are coming from (This is where you lack the ability to debate Joe, to admit something like that) But not in all cases will 10 whp be enough to show any type of gain on the track. The forces pushing against the vehicle at greater speeds might require more to do anything at all. Your point is even if its .00001 its doing something. Sure, if you want to break out a microscope to win this debate... You win! LOL.

        Were talking about real track results here though not a science lab. Not in all cases will you see a gain on the track in MPH by adding 10 whp. It all depends on the variables. At stock levels that gain shouldnt be so hard to see. An extensively modified vehicle however and it wont be that easy to detect if at all.

        Now back to a debate with some reality... The baseline E63 dyno was low compared to its advertised crank HP. 24% loss through the drive train is simply crazy. So either the machine reads low. Or the baseline was low. 447 rwhp doesnt tell me the machine reads low. Drop in filters or not.

        Please remember though that when it is claimed by a tuner, it is completely different than how the "track guys" classify it. Many of the track guys online classify it as tune-only because otherwise, you'd have a million titles: tune-only, tune-filters, tune-filters charcoal-delete, tune-filters aftermarket rims, etc....
        Bottom line is TUNE ONLY is TUNE ONLY end of story.

        I wish he would just come to the track and do some heads up runs with me on the tree. It would be so much fun!! Sadly, he has turned down every opportunity for that to happen.
        Dude lets not start with your non sense again. The last time we ran I pulled your ass twice. Even with your lighter wheels to 160. The reason why I said it was 1-1 is because I dont want to hear your BS. Its no brainer-we have the same $#@!ing car and tune. I'm lighter so it doesnt take a rocket scientist to figure that out!

        You have lightweight rotors and you weigh 120 pounds. LOL. My "Lightweight Wheels" that save maybe an overall 10 pounds total dont even come close.

        hahahah... Ahhh Jon.. 1st time you pulled. 2nd time you lost to 160 by 1/2 a car. JUST LIKE IN THE VIDEO. First run was to 140. This is why video is needed with you. This is why track results are needed with you. This is why vbox data is needed with you. Without them you lie.

        You are now saying that the 2nd run we had to 160 you were ahead? LOL. You know what they say Jon. Its not a lie if you believe it. Keep on believing Jon! Ill stick with my video proof and my track proof and my Vbox proof. You keep making excuses. LOL.

        You would have to notify your dealer that there is a tune otherwise they might flash over it by mistake if there was ever an update. Make sure you find a dealer that is tune/mod friendly otherwise they could void your warranty when you mention it. My dealership is very cool with mods and their AMG tech knows to NEVER flash my car with any software updates.

        The relevance is to the platform since it shows there is no magic being done to accomplish something no one else can.

        Bro... I meant and re-stated a couple of times that I was surprised you didn't mention it earlier (as in your first or second post) in direct response to my first post since that was the point I hammered initially. It's okay, you must've missed it for the first 2.5 hours and a few posts then came back to it. It's no biggie... you didn't have to.

        Agree to disagree I guess. In my opinion, dyno graphs are great tool to show difference in power between the mods but not best for detailing package specs. They may work okay, but just not the best way. Did you ever get a chance to get a bit more details about the tuning package? What air filters they use, etc.... I think RENNtech used AFE and Evosport used BMC.

        You have to remember.... we didn't say that there will be no gains to the engine.... we just said the gains may sometimes not show on the track as expected. And we didn't even say for all cars and all speeds, we just said that it is definitely possible and has happened in the past. The speed traps at the 1/4 mile track will definitely not show a 0.00001 difference. Heck even their 0.001 is within their error margin. So it is indeed possible to have gains on the dyno not show on the track, and it gets progressively worse for larger and heavier cars. I think (or hope) we're all on the same page on this one.

        Rep for this. Hopefully this will put this part of the debate to rest.

        I skipped most of it there were points I was going to ask what came first the chicken or the egg:: but I figured that would be a good debate for sticky and Propain

        I mean all of us mhp fanboys,no its obviously the egg and its much quicker in the 1/4 mile cause it has an mhp tune
