I am excited about this release as well. I didn't see it in the articles, how much weight are they trying to shed?

No welding & body cutting was done.

Can you share the sources that you have that make you so confident that the next C63 will be a 4.0 instead of a 5.5 litre ???

I never thought I would own a Benz.
But, seeing what AMS and Renntech have already done with the new M157 E63, I am VERY interested in what AMG is cooking up.

If the rumors that the 2015 C63 will be getting a M157, 4matic, and DCT are true, I want the car that I believe will prove to be the best daily driver available.

I have to tell you all, that after hearing from my friends about the lack of reliability and high costs of owning a German car, especially a AMG, has me terrified to own one.
But, if these rumors are true, I think the risk may be worth the reward.

No but the weight can help keep you planted when trying to control a large/heavy trailer

Eh I think the x5 is at a good weight. That thing can tow like a beast I don't think a weight loss would help that

One will provide him with bragging rights and make him happy, the other will infuriate him because of the disappointing amount of power the other dyno says he makes.

The only AWD dyno in my area is a heart breaker, then the operator applies a atmospheric compensation which further skews the results to heart break land.

It would be nice if OP posted a before/after dyno to show the delta between factory turbos and the stg2's. I'd also like to see the dyno plot just for an idea of what the power band looks like.

It does not take slop into account. It gives you your elapsed time from point A to point B or from certain speeds. It's usually on par with the Vbox when I tested them both at the same time.

agree

This exactly!!!!

Dropped my car off last week at Cobb tuning in Plano Tx. Guys over there did an exceptional job of getting turbos installed along with a ton of preventive maintenance work. I'm running The rb flash from BMS along with G5 iso. I'm am very happy with my car so far. Iam running a 50/50 blend of e85/93. Mods are FBO, Walbro e85 lpfp, BMS trunk mount meth kit, Level 10 trans. and wavetrack lsd. Also installed new eibach pro kit, replaced serpentine belts and pulleys, oil filter housing gaskets, new plugs (ngk5992), 6 new coils and 6 new injectors and got rid of that POS raceland dp for a bms. First thing I noticed is how quiet my car is now. The old turbos rattled so bad I couldn't take it anywhere nice due to the rediculous noises it was making. I have not had one single code or issue since picking up the car on Sat. Morn. For the first 200 miles I drove on map 5 and took it easy. After that I turned it up to map 7 and at first I was like this things not that much faster until I watched it climb on the speedo and wow is this $#@! fast. It is just such a smooth power delivery that you don't notice how fast its climbing. Trans. shifting is quick and crisp but not over the top.Havent gotten alpina flash to work yet due to a error code it keeps giving me but I can't wait to get it going. Not sure what the issue is but I coded my injectors with inpa just fine. Ill dig into that this weekend. It has been raining and hot and humid as hell since the day I picked it up but was able to get a couple of logs. Created this from my phone so if you don't mind Terry@BMS could you put up a log or 2 for evaluation. I will be setting up a dyno session at Dallas Mustang in the next week. Thanks to Tony@Vargas, Terry@BMS ,everyone @COBB Tuning Plano, Level 10 for the trans parts and Eric who did install of trans. Parts. I have not ran the car on any custom maps yet or my meth maps. More to come and thanks to all in the community that helped. You know who you are.

As long as it's done by advancing timing while keeping the same boost and AFR, the fueling stuff remains the same.

Love this!!!! This is what im going tonpost on the cobalt forums. Zzp tested their efr and hit 540 whp. Nobody got close to that. I stil have the dynojet record for the efr. Ps zzp has mustang dyno. Thats why
