I have a 55 shot on a d16, 93 si hb. I have retarded the timing and put stage 2 colder plugs in the car. The car doesnt pull as much as it did with the timing a dead center, does anyone know if I would get back fire, if i zeroed out the timing. I figured ask before messing **** up, someone might have done it, plus a 55 shot is really weak.

 

i wouldnt see a problem with it. just make sure your plugs are gaped right
