Ok so My buddy has a stock ls turbo eg and is runnin rc 550 injectors I was told it needs a resistor box is this true the car is tuned I figure if it's true the tuner would have said somethin idk plz lmk wat u think it also bogs dwn if u speed shift into gear it will bogg dwn a lil then pull also jus found out he's runnin wrong plugs and wrong gap on them anyone know thanks HT

 

Depends if he has "saturated" or "peak and hold" injectors.

Bogging could be alot of issues. Its most likely tune related. Who tuned the car?

 

Tuned by church out here in LA

 

Also how do I tell if there saturated or not
