I think I will feel gains above the placebo effect. I have done some pretty solid mods to the car, intake maf porting, iat 5 ohm mod, tb butterfly bar cut down, sho shop stainless y pipe with cat, no res, 6 inch k&n modded with same size intake diameter as the maf bolted straight to the maf and a chip. sorry to say it but the bat intake pipe does yield more than 1 horsepower. More importantly, it smoothes out the powerband, and no I do not have dyno proof. it really doesn't matter anyway, i like it and i was just sharing info.
