I thought the module itself either works or it doesnt, car probly just needed packs and tune up and would have been fine... ive never had one fail but replaced it anyway : )

funny my module always fucks up but the coil are good, I reuse the coils and swap out the module.  The module will make the car do strange things.........one time at WOT only in 3rd or 4th gear around 5k rpms it would fire the wrong cylinders and detonate like motherfucker........the car would lose 10mph at 60  mph instantly.  Scary stuff, but boy are these motors tough!  It that was a 4 banger it would have sent a rod through the block!

Module sucks if I have another bad one I'm buying a new one from GM!

I think mine tooks the shits today.  Tach turns off and starts bouncing around when it backfires and sputters. MF  :icon_evil:

NO WAY,  on my stock tuned car, i get some pretty loud detonation when i have the boost controller up too high and i run the car at 95% throttle just messing around, but the other day i had the boost set way too high for the stock tune , hit boost cut at redline.... the loudest backfire ive ever heard outta this thing , i let off it,  it coughed , the tach dropped for a second, sputtered and continued to run... i was amazed i had 6 pistons... do you have any knocks or does it have a dead cylinder now?

Well messed with mine again, still did back fire. I changed the map sensor and it went away.  :icon_confused: . Bad sensor I guess. I'm still going to replace the crank trigger, wire and ICM.

Hope everything going well for you doggingred90
