I was a few seconds away from doing this myself. Then last Year Mike Dez Racing out of Mass. tried tuning in a recently ported, polished, extrude honed Mach1 intake & couldnt find a nickel more of power over what they already had with the spacer & exhaust & CAI etc.. They got the PHP $1200 deal & did some other "work" while they had it all apart.. After it was all said & done they couldnt make anymore power than what they had before..
Maybe the Superchips tuning software has more to it now that can take advantage etc. but last year they couldnt do anything with it using Superchips tuning & his Dyno.. these guys have seen gains from good port/polishing before & the pieces they got back from PHP looked awesome but no gains found?? They tried everything on the dyno they could think of & nottin seemed to help at the time.. The guy who owns the car is a member here on the registry. Not sure if they ever got anything out of it to this day.. It was as though the Mach1's intake just didnt need it.. Maybe Dave will update us on that deal.. Im still interested & the winter IS going by pretty slow! For $450 id like to at least try it to see how it goes on mine
