I used the search function and did not find anything useful. What is the best ecu re-tune or performance chip for the 545i?
I found these guys in NYC, F1 Tuning that claim their mod increases 30hp. Sounds real simple. 30hp with 1 re-tune for $645. Its a really bold statement considering the bang for the buck...... I'm going to call Monday to see how legit they are.

Yea but how can they claim 30hp. Sounds like a load of BS.. They claim big gains on other models too.
