| Re: EFI brute force chips? any suggestions or waist of time? The PC3 seams like the one that is the best out there for tunability. The ones on e-bay for $50 are a scam. They want you to tap in to the oxygen sensor or something. I have the Optimizer and all that does is adjust your fuel intake and nothing perfomance wise.
