One item to note on the S4 B8 ECU, it is very adpatable. It learns and the response depends on the way it was driven in the near past past. I am not sure how long it takes to settle into the most aggressive mode. I know, when put in dynamic & then after driving aggressively for a few days, the throttle gets very aggressive (the throttle response can be brutal).

A test drive on a B8 S4 car driven mildly in the recent history, will not show the rapid throttle response.

I think I was trying to be a dick on that particular post. Other times it may just be a co-incidence.

Circuit Tested came in here comparing the B8 S4 mod market to the mod market available for a tiny 2 seater track day car as if it's relevant...and then went on about some headers testing he did that was random and TOTALLY unrelated to tuning the B8 S4. If he would just RTFS he'd see that I was mentioning that the tuning solutions available for the B8 are horrendous...there's only 1.

But hey, go buy the Strat Intake and the EuroCode headers based on CT's 'testing' and tell me how it goes.

good point. This car however was my friends car, and he likes to get on it. He's observing the drive-it-like-you-stole-it break in method recommended in this thread...
