Im installing my maf(77mm pro-m), injectors(24lb FMS) and pump(gss340 255lph hp) this weekend. Will these have any issues with the stock computer? I will definetly let the comp relearn by unplugging the neg post on the battery, but will i need a retune? Im getting ready tor a TFS top end kit, so i cant get tune until i have thew whole kit on, but i want to get these mods on now. Thanks alot.

77mm mass air is way to large even with the heads and stuff you have planned in the future. Just m .02 Good luck ![[patriot]](graemlins/patriot.gif)

well, i can downgrade size sooner or later, but i just want to to know if i upgrade my maf and injectors for a pro-m calbrated for 24lbers and is the appropriate calibration for my year of car, will i have to get a custom tune for it to work properly?

Nope as long as the MAF is for your year car and is calibrated for 24# and your running 24# injectors you won't need a chip. You'll only need a chip with a matching MAF at around the 42# mark because the stock ECM has trouble adapting there..
