You would have to be retuned more than likely.One,different manufacturer injectors have different latency values and better fuel atomization = better burn = leaner AFR(possibly).Cobb has an injector calibration worksheet on thier forums with most of the major manufacturers and their latency values.

alright cool. i think i'll just try out the modded stockers since so many people have had good results. so far i've had great luck with all my mods, even when i didn't know so much what i was doing. so i'll just bank on luck.
