Well, I got my GTO dyno'd saturday evening late at MTI. It dyno'd 289.6 rwhp. I really wasn't that dissappointed since it didn't have time to cool, meaning 3 mins after I got there it was on the dyno. Add in there being in Houston traffic with the A/C blowing doesn't help as well as me staying in League City, which is roughtly 45 mins to an hour from MTI. The second pull yielded 280.6 rwhp and the software wasn't acting right so I couldn't get the torque numbers. They are going to redyno it next weekend so I'll get there early and let it cool off properly. I have an M6 and going off everyone's dyno sheet here, it should dyno between 297 rwhp and 305 rwhp. I think the power loss was from it not cooling off, what does everyone think?
