will I need a new prom?

I know I will make the best of my upgrades with a new prom, but will I need a new on if I just do headers and an intake?

Thanks-

Eric

A custom prom will help even a stock engine. But you will not need one for those two mods. The stock chip will be fine. __________________ 377 RWHP, 390 RWTQ (05-21-11) 12.803 @ 108.50 MPH (1.923 60') (04-11-01) Work: Manley Performance Products Founder: SoCal Thirdgenners Founder: SoCal TPI Organization
