Wow, that is a pretty good time. I know, it's about a $48,000.00 replacement engine . It has gone through my mind a million times. I did buy the car to go quick. So, I am probably going with Eurocharged stage 2 and downpipes. I have never tuned a car before and I hope that is enough. If not, the plan is to send out the turbos and get a new intake and a few other supporting parts. But, let's see what happens after the tune. I am using all Eurocharged parts and they say I get a $50k warranty on my engine for 2 years (I know they probably won't pay, but it makes me feel a little better). I will find out tomorrow for sure if that is the plan.

Wow, that is awesome! I just checked out the tcu/cpc module you listed. Do you feel that made the difference? Do you feel it is too much torque that may cause you problems later?

The CPC makes a huge difference. I ran a 12.0@114 before the TCU/CPC. It's definitely a lot more torque, I wouldn't call it too much. But then again, I just came from a 700hp/700tq Audi S8 so my baseline maybe skewed.

3.5 sec 0 to 60 and 11.25sec at 120.87 mph are a great 1/4 mile times.
The best that I was able to run stock was 11.7 sec at 117mph.

Whowza! you just can't sneak in a TCU tune low key like that. That is huge.

That is a missing key.

Ya it's a huge difference on the 9 speed MCT. MB really tones down the output via the CPC.

Man, some of you guys are ripping awesome times. I'm definitely going to upgrade the turbos, downpipes, and get Water/meth injection with a 91 tune. I will 100% get before and after dyno sheets.
