OFFICIAL Seoulful Racing (SFR) ECU Reflash For Sale NOW!!!

If you look stock to the wheels is 160... with the tune its 200 to the wheels... thats +40 regardless and that's what matters. At least you know a civic with bolt ons won't be able to give you a run for your money.

Hmm good question, I'll be pumping 87 octane... could the ecu adjust itself and increase its performance on the day i pump 91...
