I only have a custom mufflers (axelback). Everything else is stock. I do have meth injection, but it is disabled to not skew actual tune numbers. This is what I mean, I saw that sheet you sent, and keep pointing at AFR as a potential culprit. I put 50/50% 93octane (which is really about 91), and 100 VP racing fuel. Balances out to abou 94-95octane. So fuel should not be the issue.
