i have the mac straight shot mass air system (the one with the maf) and i seriously doubt i got 20 hp from it..at the exagerated most i prob got 15...but im guessing 8-12 hp....that said... i was very pleased with it i would recommend it to anyone...my only complaint is that the filter has a tendency after a few weeks of driving to come loose from the rubber tube connecting it to the maf. Ive had to put it back in place and re-tighten it 2 or 3 more times already and ive only had it for about 2 months now.
