kennyfrc- Agreed that I have yet to see any tune exceed stock for peak hp. Even my friend with ESS on his Z4M with headers and BMS cans and x-pipe dyno'd lower than my stock.

mfanatic- I doubt Remus cans do much to affect numbers.

Blind32- I gave it a day of driving (~80-90 miles and 3-5 restarts); and on speaking with AA they said it should be fine. But I do agree that there was some adaptation going on at the dyno with WOT runs.

johannes- Sorry, but no AFRs; dyno place wanted to weld a bung to do that and I did not want to bother with that.

Rest assured, that I am not done yet with analysis. I want to try with some 100 octane thrown in to get a richer fuel mix to see what happens- if timing is too advanced that knock sensor is kicking in, then a higher fuel octane should clean that out.

I will also throw in new plugs and clean out the intake some. If not much changes, I will go back to stock tune and try again.
