• 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

        I'll watch the game but the Browns score 14 points a game. On paper this should be a blowout.

        I can understand that. Most of the time I just want my beer and the game and no interruptions.

        Nobody was talking about tuning for a supercharger at all in this discussion or carb approval for that matter, so not sure why it is being brought up here all of a sudden. Your implication that they are doing things that were thought to be impossible with tuning have shown results to be on par with everybody else.

        And I replied a few times that most tuners who've released dynos were showing gains of tune-only. So we'd have to dyno a car with the air filters being used in this incident to gauge to see if there is or isn't.

        Again, I didn't blame you for it.... I pointed out that you missed it as well in my first post and your first couple of replies to my post and NOT till I kept repeating it that you said anything. It's okay man, we all make mistakes.... no biggie Click here to enlarge

        Honestly, I'm surprised you made such a broad erroneous assumption despite your exposure with the M156 engine so far. I'm starting to think your exposure may have been limited to surface level or basic stuff. Such an error should be left to rookies Click here to enlarge

        Not sure which comment you are referring to here.... one can tune a car without changing filters at all. Then one can tune a car and try to optimize a whole bunch of stuff. Either way, results of the "magic" tuning seems to fall in line.

        Not really, as I pointed out the brand name of filters, charcoal filters, intake mods, etc.... were all items that were not detailed or even listed as a package contents somewhere. If you think the graph should include everything info out there, that's your opinion. I think the graph should include main points, then package contents and specs should be listed separately.... but that's just my opinion.

        Yep.... although not a defense since that was only an observation I made. I hammered a point, you completely missed, then replied about something else, then I hammered it again, then was caught 2.5 hours later. It's okay, I'm not sure why it's bothering you that much.

        You remember when I first dyno'd the car with 550 hp on pump gas and the number of people on this forum who called BS. Even after I posted the dyno sheet not one person say 'sorry, you were right', it was 'why didn't you post the slip to begin with'....not even acknowledging what I said was accurate. The only reason to post here now is for entertainment value as every thread turns into the same two or three people arguing back and forth about something completely different than the OP.

        And don't worry, I won't call you a prick (at least not to your face). I am already thinking the road trip from OC to Florida will have to go via Vegas for two days to be sure all is rested for the rest of the drive!

        Actually, you seem to want your hand held even more because the implication in his statement was that the hp was not lost and I stated that it'd be impossible to fix all conditions. If you wanted him to state all that in the statements, then you're requiring the same courtesy.

So what is the misunderstanding again?
        Wow, I can't believe that you are still using an equation that does not take into account many of the elements which propain listed into account to misunderstand a point. Do you really believe that equation takes into account all physical conditions on the track? I certainly hope not.

        I was under the impression that NHRA only uses altitude (not weather) for their corrections (or at least that's what was on their website). I'll have to look it back up. However, real world conditions include air speed at the end of the 1/4 mile as well. So if the car reaches 150 mph at the end of the 1/4 mile then it'll have a lot more resistance on it then a car that reaches 100 mph.... all these factors that may hide the gains.

        Actually the ECU can certainly pull timing for one reason or another causing the a reduction in power - and the ECU programming is not mechanical at all, it's electronic.

There is no way this can not happen as already proven although it should have been obvious especially for seasoned drag racers.
        Seasoned drag racers know that it's almost impossible to fix conditions from hour to hour let alone day to day, and that with today's complex engines, many factors can affect the results one sees on the track.

        What I'm saying is they have a grasp of the ECU others do not. NA tuning is a step backwards for them, less complex. If you weren't in such a hurry to call the results improbable you probably would not have made such a big mistake. In the future, keep in mind what they have already done so you can avoid these errors.

        Well I'm sorry, the dyno is with filters. That is what is provided.

        What are you talking about? Seriously, I didn't make any error or miss anything, YOU DID. Get it? You messed up, you screwed up, you had to backtrack. It really is that simple Mo.

        Seriously? You are telling me not knowing there is a separate charcoal filter in an engine I don't own is a basic mistake and that applying my own experience is wrong? Sorry I learned something. But at least my reading comprehension makes up for it. Talking about basic errors....

        Why I'm referring to is that perhaps the air flow requirements with how they are tuning require a change in the filter to see maximum results. Sure, you could tune without changing the filters. They didn't, so expect gains with filters, simple.

        So more information on the graph would help you somehow in not missing the small bit that was already there? Makes sense.

        Nothing is bothering me, I'm just surprised you aren't taking accountability for your screw up. Pages after page and you didn't even process the graph or my post. Then you wrote I failed to mention the filters when in fact I did, another mistake you did not take accountability for. Any time now would be good.

        The factors won't hide the gains, they will affect them. Two VERY different things. There is no such thing as hiding horsepower gained, I don't know why you do not understand it. You are fighting a lost cause but keep going I guess.

        If you run with added horsepower and you don't see a gain from a run with less horsepower then subtract those horses in those same conditions and you will see it. Why is this so tough to understand? What part of it do you not get? It is a mathematical relationship that no matter what variables affect it must exist. The horses aren't hidden and they don't wander off. They have to be in play. You have people who studied physics telling you this same thing.

        Never said an ECU was mechanical I said a mechanical failure since apparently we are exploring even ridiculous variables in an attempt to change the laws of physics.

        If power is reduced you will see a change. If power is added you will see a change. Thank you for proving my point with pulled timing having an effect.

        No kidding which is why as DA changes throughout the day you see different numbers. You may notice when the car, especially naturally aspirated, is gulping denser air it is running faster? How is that possible? Why were my fastest runs in the best DA of the day at the track? Ya, thanks, my point exactly. Somehow my additional horses were not hidden and we are talking smaller changes than 10 whp from hour to hour.

        Horsepower gains aren't going to show up on the track, right Click here to enlarge Maybe gravity was off that day.
