Finally got the GTO tuned. Brent at Dyno Tuned Performance did a great job and you couldn't ask for a more honest and down to earth guy. First pull with the boxed tune was 433hp/45Xtq. It took him almost two hours to get the A/F down from 10's to where it is now. Here's a quick vid of the last pull. He said it was a Dynex?? Dyno (the kind they use in Australia). It was roughly 78* out with 48% humidity. I was fairly surprised with the numbers for what my mods are and he seemed pretty impressed as well, especially with the torque numbers.

I'm happy with the numbers but more importantly it runs so much smoother now and it doesn't smell pig rich as I drive. Plus, it looks like the new Aero 340 is holding its own after all.

Nice results! My friends 06 GTO put down the same numbers. Congrats it's gonna be screaming! I'll tell you one thing, if you speed shift and it hooks good the tranny will go. Ask me how I know.

Nice numbers! My buddy has a Maggied 2004 CTS-V making a little less than you and his car is fast, so the GTO must RIP!

My GTO with the M112H stock pullies and catback from LPE made 458/453wtq SAE on a DynoJet 248H. Ur not far off. Add a cam and up the boost to break 500whp

60 rwhp for two hours work? I'll take it.

I'm mildly surprised they left that much on the table in the boxed tune? I understand the package deal coming with a conservative tune so shadetree jack and myself don't blow things up, but leaving out 60 rwhp?

...anyways, looks like a blast! congrats!
