I've had issues with fuel cut. All depending on the weather. Fuel cut with the new ATP wga is really good, won't hit cut unless it is below zero at full boost.
before I fixed the wga (the stock one was broken):
with the unichip at high boost (13+) I would hit fuel cut at anything below 50 degrees and it would hit fuel cut at any psi in freezing temps.
I got the wga fixed at the end of last summer and fuel cut has disappeared this winter. I'll see if it comes up this summer when I start pushing a little more boost, but really the car has run amazing. I've had it since new and its been a great running car.
basically the fuel cut does what its supposed to do.
