• 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

        Im very anxious to see what a Weistec tune-only E63 traps,if it did actually gain 47rwhp it should easily be in the low 120's.

        Im not going to get involved with this endless debate;Im just going to wait paitently for the dragstrip results,but even then Im sure the results will be debated endlessly with the: "well,if it was at MIR or Atco instead of on the West Coast it woulda went much faster" lol
        Ohh stop your crying... LOL

        Jesus you guys $#@!ing is really getting out of hand and super annoying.

        I'm going to try and get my car over to Weistec before the holidays and get this tune but I doubt I'll be able to get any 1/4 results for you guys so dyno numbers will be it...and considering the past 5 pages I doubt that will mean much LOL.

        Sorry guys... I didn't mean for this to get out of hand as it did. I posted a small comment of my opinion regarding the gains on different cars but then it turned into a big ordeal. I also apologize again to Weistec. Hopefully Sticky will move all the arguments to a different thread so we can keep that we can clean this one up.

        Luke, your car is still stock? For some reason I thought you had long-tubes already. If you're still stock then your car would be a good test for this I would think Click here to enlarge

        I'm pretty confident that weistec can deliver. This exeenom fellow is just coming out of nowhere and thinks he know stuff, when he doesnt. Your coming in here making claims about a tune that you haven't tried or seen. Weistec claimed a 538rwhp for a fully modded 63, when in fact guys are making over 600whp with thier mods.
        When you tune with them and find that you are getting less than what they claim, then come here and show us your findings.
        I am sure you will look like an A$$ In the near future, and I will bring this post back just to remind you. Sticky, please keep his posts and don't deleate them.

Take the Veyron for example.... it needs only 270 whp to get to 155 mph but then it needs another 730 whp to get the next 100 mph.
        I think you confused terminal velocity and trap speed here. 10 whp assuming equal situations will show, obviously variables affect output but added hp vs. that same hp not there favors the added horsepower always.

        This is not true whatsoever. Exeenom has spent a long, long time on the MB boards and I have spoken to him many times be it in person, on the phone, or on forums. He knows a great deal about this platform and you would be wise to read more than type right now on this topic.

        Drive in that traffic and tell me that.

        It's close, obviously, so I'm joking but it's an annoying drive beyond belief through LA.

        actually what Mo is saying is correct, but the term he should be using is displacing air, the faster you go the more HP you need to displace the air. What he is absolutely wrong about is not noticing a 10hp gain. He is correct that if we were doing top speed testing that 10hp would result in little or now gain, maybe a mile an hour or two but that same 10hp will be very noticable in normal around town driving and on a 1/8 or 1/4 mile drag strip. Some of his argument is valid but some of it is not.

        No need to apologize, Mo.

        And no...my car is pretty much stock less charcoal filters and secondary cat delete. I'll probably go with a tune first to measure gains and then asses the idea of long tubes. I want to keep my car as close to stock as possible.

        I have a cold/flu and all of this reading is giving me a headache. Let's just sit back and see what Luke gains from the tune.

        That's what I've been saying.... when you encounter a low-dynoing vehicle, at some point, you have got to start diagnosing it. The mentality that it's naturally low may not work. Even Jim stated that the 394 whp figure sounded too low... the engine in the CLK63 BS has the same 507 whp rating as in the E63 and CLS63 and on many dynos, the engine have shown 410 to 420 whp.



        Again, that's what I've stated before, that the there could be reasons one car is dynoing lower (or higher) than it should.



        Nope.... I said if the cars were identical... which meant same tires, same tire weight, same tire pressure...



        LOL... I never said unhealthy cars don't exist. I've seen some dyno low, get diagnosed, then dyno higher on the same dyno at the same shop. This does not only apply to E63s, I've seen it on many Mercedes models.



        The tune won't cancel out the effects of different elevation or weather conditions.... and if the car somehow adapted to the less aggressive timing of a driver, then most likely after the tune, it will re-adapt again to be less aggressive to the person's driver. It may not go as low as factory, but it will go decently low in my opinion.



        I'm glad you got that.



        No Joe.... they advertised a +47 whp gain for their tune on an the E63 platform. Many companies handle this differently. If a tune for some companies produce 25 whp gain on a 420 whp car and 50 whp on a 380 whp car, they advertise their tune package as 25 whp gain. Others, advertise it as 50 whp gain. I stated before, it is a matter of choice.



        The burden of proof here is not on the customer. If a company claims their tune will produce 47 whp car, then they may have to show these gains on a variation of cars. Otherwise you're saying that they are only advertising that their tune will gain 47 whp car on this specific E63 on that specific dyno with that specific mileage, tire pressure, weight, etc.... To me, when a company advertises 47 whp gain, it is understood that they'll be about a 10% variation from car to car, which equals 4 to 5 hp. But 25 whp variation may not be expected or accepted by many.



        That's why it is always good for a tuner to go through many dynos of the platform and establish a healthy average so they know when to diagnose a car if something is wrong.



        When I asked them, they said they asked the customer if they wanted the dyno to read like a dynojet or with load so it can read like a dyno dynamics, and they said most customers want to see the higher hp so they choose the dynojet style, but it's not that they think their car is broken or something.\ind of weird my lack of exposure was able to find a lower reading graph from a stock car so fast. I also believe I have spent plenty of time in the M156 section and created and maintain one on the motor. So I do not think I'm lacking exposure.

        Not weird at all.... anybody can find a dyno if they know how to type on google. So lack of exposure has nothing to do with it. Heck I can get a 3 year old to find a dyno online. I'm not sure why you think it makes you high exposure.



        Hmmm... so now it's personal because I own one. LOL... common buddy. A few people already stated that dyno looked a little low, so it's not just me. It's only that thinks the 394 figure is perfect. I personally don't have to portray my motor anything. I actually dynoed and tracked my car in at least double as many places as you have your M3. I also have seen and helped other E63 improve their dyno and track times. I know how much my engine dynos and how good (and bad) it does in many conditions. And it's because I own one, I was involved in many of these events. And you know this more than most.



        I already told you multiple times.... from their experience with so many Mercedes dynos, the majority use 17% to 19%. I've asked them in the past, but you can call them and check for yourself. Call RENNtech, Kleemann, Brabus, Carlsson, Evosport, etc... There's only one company so far that told me 20%.



        Again, that's what I've stated.... that the two cars would still not be on the same level after the tune because the tune can not fix what the slow break-in caused (improper ring seats). So the tuner in this case adjusted timing and air fuel, which is usually done on any car regardless of break-in. So the part that is affected by the slow break-in will not get changed by the tuner through software.



        The same goes for tuners... we don't know if the car was dynoing low because of a problem or something else. Maybe the dyno was manipulated to read low, then after the tune was re-adjusted to tune high. Just like guys are obsessed with higher numbers, tuners are obsessed with higher numbers.



        Yes, and since some customers may get less and others may get more, some companies choose to advertise the less numbers and others advertise the high numbers, and others advertise an average number. This way the customer is not shocked when reproducing the results.



        Agreed. But I think our discussion deviated a little bit from the original topic so it maybe best to continue the discussion in another thread so we don't pollute the Weistec thread more than we have. Can you start a different thread that we can continue this in?
        I'm not going to respond to all of this Mo not because I did not read it or care but simply because I think people just want to wait and see another set of results. Just best to wait for those I think.
