i have a NA-T Auto which is on about 11psi of boost running the DET3 piggy back. When boosting the car is running strong but once you come off throttle and crusing it is like i am having fuel cut. so when i am driving normally the AFR will go to --- and then go back to about 13 when not boosting. when it goes to --- it like the engines dies and has no fuel then it will just come back on again. Same thing if i am in nutreal and rev the car it will cut fuel at top revs while standing still. Does anyone know what this could be as it is getting abit annoying when you driving down the road normal and it jerks on and off.
