It's working great, when I started modding the GTP, I wanted a 14 second car at this altitude. I'm probably at the mid 14's now that I have it tuned. I still need to take it to the track and test it, but it was running flat 15 without the tune, it should be there by now.
I bought a SSIC here in the forums, it's in the mail, that should be the last engine mod, it should get me in the high 13's at least, which is more than I could have expected when I started.
I don't want to go any further than that, because the parts needed are much more expensive and I would definitely need a transmission that can take it.
But it's all thanks to the advice I've received here on the forums.
