I had noticed a torn coupler and noticed the car was fuel cutting under boost, after a while it had popped off and had not boost, but it wasnt cutting fuel either. I had to drive it like that for a couple of days and wait for a new one to come in and i put the new on on and its cutting like crazy while under boost. I checked all the other couplers to make sure no others were torn and none were, i then checked my WGA to make sure it wasn't torn, and again it was fine. Now im getting really frustrated with this car and have been trying to find someone with this exact problem and have not found a solution yet. I have a custom FMIC and piping, greddy BOV, relocated MAF, and the APEX R1 turbo back exhaust. Im going to try cleaning my MAF tomorrow and see if that doesnt help, but before the torn coupler the car was running fine (it had the ever so common hesitation issue, but other than that ran fine) anyone have any input here?
