RE: Underdrive Pulleys or Intake?

you could always call your shop about a dyno tune, but i dont think it'll make much of a differance with the limited mods (not saying mine has so much more, lol).. but the way I was advised and followed was... CAI, tune... then I got my TB/Plenum, headers, pullies, midpipe, mufflers. Like I said, I went from stock w/cai and tune, to full bolt on before I am putting the money into a dyno tune.

so whats the best way to tune your CAI... i have diablosport.... get dyno tuned??? right now i have there tune with timing up 10% and rear o2s off, speed limiter off.....

I think the factory on your car is 10 degrees advance, so 10% is 11 degrees. If I'm correct, you can go to 14 degrees total with better gas and see more gains. I run 89 with my timing at 14 degrees, but 91 or 93 is recommended.
