I'd have to have the ECU re-tuned. Once I have that done and maybe add Mike Smith exhaust manifolds, I can't think of anything besides larger turbos to get more HP. I see some Z's at last year's Nationals and on the web that are hitting over 700 RWHP. I'm just wondering...besides me doing the dual-pop w/ re-tuned ECU and exhaust manifolds, do the larger turbos really put these people's Z's at that 700 mark?...if not, what else could really be done to achieve that? (heck, that convertible TT at Z1 hits over 1,000 rwhp....what the hell is done that really adds almost 600 hp more than most Z's out there?! lol)
