ok so 92 with straight pipes, ever since the straightpipes i sometimes experience popping under heavy acceleration on the 1-2 upshift and i occasionally get a slight stumble when i nail it and it kicks down...not all the time but some times it will "cough" for a second then take off. I deff love the way the car sounds i just want to make her run alittle richer. does anyone know if an off the shelf hypertech chip will do the trick or do i have to get one custom chip burned? my dad says run a colder spark plug>>any ideas??? im loosin my hair here lol
