Fuel Additives?
I'm wondering if any of you all with chipped A4s have tried or used fuel additives/octane boosters. Fairly good 92/93 is available in my neck of the woods, but since the chips are supposed to be adaptive, I wonder how much of an improvement vs. risk you get when moving up to say...100 RON?
Anyone Anyone Anyone? BTW, we have a MTM Stage 2 car.
