I was trying to keep up with the tuner (Sam Shalala at ProTechnik) as he was adjusting the fuel but even after taking the EFI101 course and with my engineering background I could tell there's way more to it than taking a class or reading a book. I think using a good tuner is worth more than money spent anywhere else.

I'm not too optimistic about acheiving 500hp, but it's there Sam will find it. The AFR's are still a bit rich in the mid range so there's still some work to do there. There's also a lot more work to do on the timing. Most of the time so far was spent on bottom end work. He got rid of most of the dead spots, but said we need to do some tuning while driving to make sure they're all gone. I think he wants to do that before he does the top end work. I was just happy to hear it run, more like hear it wail. The scream was fantastic if not painful.
