i just read about the latest stage 2 upgrade for this audi 2.7biturbo engine.
it includes air filter, chip and cat back.
rated at 320hp!!! 360 torque!!
the whole upgrade is less than $2000!
14.5 psi!! how much stress can this have on the motor? what could the long term effects be?

i guess i am still waiting for Mercedes to come out with something that isnt in the $70-80K range of the E55. is the C55 going to ever come out? (probably not, it'll just canabilize sales of the E55)

take care
