Default 335i malfunctions - 08-13-2015, 05:11 AM

Hey guys I have a stage 1 turbo running pump bef running race gas (no race flash) and map 6 set at 20s psi tapering up top. I did the 5_8 update and bef at the same time and ever since the car has been occasionally throwing engine faults and car has also been backfiring alot anD sometimes misfires. Coils are new plugs new dealer replaced a couple injectors so all that is ruled out. Yesterday doing some runs car thru a code (didn't have laptop) and went into a limp mode. Turn car off and on and it went away...

anyone know what's up I heard recently people have been throwing underboost codes but I think it's because I'm running pump bef while boosting 20lbs.

You know what. Pull the engine cover off and check the first few plugs to make sure they're tight. I recently had the same symptoms. Started when changing flash. Turned out my plugs weren't even finger tight!
