I just recently installed an FP red and o2 eliminating DP and I'm guessing my clutch is slipping now. However, its a little weird how the rpm oscillates imo. Is this a common mode of slippage? boost is 25-26 psi afr is low 11's. In the 1-2-3 pull image its just wastegate pressure, ~19psi and it feels like its slipping when I shift to 2nd but it doesnt in 3rd which should be more prone to slip. The 4th log (4th gear pull) had 7 counts of knock associated with the oscillations at the end of the pull and 1 or 2 counts with the oscillations mid pull.

Any ideas?

Also, I expected higher load with the Red at 26psi. Is this normal? Could a leaking bov cause these oscillations? I will install a synchronic this weekend and see what that does.

Ok, I crushed my bov more and it seems to have solved some of the issues. I got a clean 1-2-3 pull and a clean 4th gear pull that felt real strong (25psi) so I doubt there is a clutch issue.

But shortly after that I tried to do a 3rd gear from 2500rpm for VD and at higher rpm it started cutting out. I guess its blowing out the spark. I am on original coils/wires with 105k miles. I'll check what my plugs are gapped at, I think .020 is what I set them at last.
