Got an 05 GTO M6 and at 2000 miles added a New Era CAI. Now car feels off. Runs fine just slower, slow enough to get beaten by friends stock 95 LT1 auto Vette. MAF is fit properly, wires in place, no other mods. Wondering if computer is just dumping gas to compensate and needs a break in period? Car seems fine other than the loss of go.
