Fuel Cut After MAFT Tuning

[Chaoticdopey]

OK well me and my friend started tuning my car and it was running super lean at idle with the maft, so we slowly adjusted it to where at idle its between 14.5 - 15.2 on the AFR, at WOT at around 4k rpm im at 11.2 on the AFR gauge and at around 4500rpms i hit fuel cut in 2nd and up gears, i have a leak detector smoke machine and saw the J tube from the turbo had a leak so i put a new gasket and ran smoke through the intake, crank case, and turbo and found no leaks at all, but now the richer the car is running the faster im hitting fuel cut or at least i think its fuel cut, i hit a brick wall for a split second and get power back... i dont fully understand how to tune with the maft but my friend just gave me a PALM Logger for the car which im going to charge and hook to the ecu and send logs here and maybe you guys could help, but for now this is all the info i have.
