was looking at KaZ's dyno #s. he did 335-340. He has everything you have minus the driveshaft and the boost controller; so his boost is only 14.5 i think. Depending on what boost your running, If i remember corectly every PSI is good for about 15hp. Also gotta remember every Z is differant; seen flucuations of like 40hp between Zs with the same mods. You should go spend the $50-70 for some real dyno time.
