Nice coverage of a good general tune for this swap. I usually enjoy creating my own but it is still nice to see what some other people are doing. I just think it would be cool if you could get some footage of just the car doing a time trial lap or something without any music at the end, to really hear what it sounds like.
I like the GTO personally. But either way just prepare for some serious turbo lag, so whatever you do you need to keep the RPMs higher through gearing.
