Im the guy that helped him put this together / tuned it for him (hptuners is my love child anymore)...

Remember when I sat there and toyed with the broken gas cap lanyard for a min or two? I probably cursed it. Also fyi I actually posted a small thread at one point about moving the idler and the zzp single belt setup to get more belt wrap. It looks like it should slip like hell but when I had the exact same setup (Litterally exact... I sold mine to him) on my genV my boost was climbing all the way to redline even on a 3.4.... Easily was making 12psi on stock heads with rockers only.
