Software
Guys,
I'm now looking to fiddle with the ECU in my 05 S4. I've benn looking at APR, GIAC, OCT........ I would appreciate feedback from anyone who has any of these software upgrades. Right now I'm running the HyperFlow Intake and a Milltek Cat-back. I'm in CA so 91 octane fuel is the best I can find without going crazy so please keep that in mind when commenting.
Appreciate the help.
