It seemed like an expected outcome given what Scott at Rosso told me. Bigger piping changing the way it builds boost. I'm still on the stock tune though. Hopefully all will be well once I get the intake and tune installed. Not looking forward to messing with the wastegate, but we shall see...@walan I've been running the EC PH2 for over a year now...similar build to yours. a few differences. I understand your explanation but don't think that the addition of the FMIC, without a tune would result in such a drastic lag. That being said I'm no turbo guru. hence my initial question.
aloha and mahalo mike
