They wanted data logs to adjust the tune, maybe offer your logs to AFI and see if they'd be willing to help out. Granted they never got mine smoothed out, which is why I broke down and took the tuning plunge myself. I'd at least try contacting them to find out if they have any incite. If not, the guys here are extremely helpful and will help when they can!! Best of luck
