ive done allot of looking around on things to do, ive tried new coil pack plugs wires vac lines, grounding issues, no codes, it runs, boost presure is good at 15psi just spitters and backfires sometimes. the car is stock nothing special, anyone please help im running out of ideas thanks

 

do you have a wastegate or any type of turbo mod?

 

everything stock wastegate turbo everything lol

 

i dont know then that sounds wierd. my car would do something like that but ony when i put my new wastegate on and it was over boosting take it into the dealership and have em run a diagnostic and try resetting the ecu. it sounds electrical to me just a geuss but by the number of responces already its the only one so far

 

check your plugs. That coil pack has been known to go kaput as well.

 

yea that was the other thing i forgot if you have the stock coil put it back in.
