Tune only 5.5L TT AMG dyno

thats one hell of an engine, just wow.

these things will be pushing 700whp easily, thats nuts.

The car with this power is capable of running 10's. That is incredible for a heavy family sedan.

Where are you getting this? At no point is the stock tune making more power?

But anyways, that is unfreaking believable. I mean really, 620/670 hp/tq to the WEELS with nothing more than a tune? That is legitimately twice as much power as my JB4'd 135 and my car is freaking fast. Nuts.

+1000.

I think that guy is reading the graph wrong!

I know the numbers are staggering, but the hp/torque curves actually look the best for the stock M157 tune withOUT the performance pack. I would prob stick with that - it's the most efficient use of the engine's power, tranny and drive system.

when u start jacking the numbers way high by just increasing the boost, u lose a lot of the linearity of the power increase. I would rather invest the money in a car with better tranny, tires, wheels, ??AWD, anybody??
