If I'm going to be replacing my stock fuel injectors (crossing my fingers it will fix the low-rpm stumble of death), which should I get? I belive the stock injectors are 24# ones, if I were to upgrade to a 26 or28# injector would my car need reprogramming? Also would i get "any" gains at all from going to a larget injector? My car is pretty much stock save a few very minor mods.

If you went larger you would need a reprogram. If you are running stock heads/cam/internals stay with the stock size injectors. No need for anything larger.

BTW - what makes you think the injector change will cure your low end stumble. What else have you eliminated to come to the injector conclusion?

Changed the O2's, Seafoamed the internals, plugs replaced so far... Just trying to weigh any other possible reason on replacing them sooner rather than later. Ive also experienced backfires down low and identical symptoms to the guy who posted in the lowrpm stumble thread and later solved it with injectors. I've eliminated springs/not enough fuel/fuel pump because those I dont think would play a big factor at low rpm if the car runs great at High. Cleaned the MAF sensor with no difference, and replaced the intake elbow which was torn before. I think its only the MAP Sensor and injecors left.
