think i might be runnin a little lean with new intake and exhaust. need some input about bumpin up my fuel injector size. and yes, i know i need an AFR gauge.

Its very very doubtful that with an intake and exhaust that you would need to change your injectors in any stock motor. You could tune your fuel maps in HPTuners with a wideband o2 to richen it up a little but it really doesnt even need that at this point. You dont need to worry about injector sizing until you begin to play with the engine, things like head flow, cams, and/or boost.

sweet. was jus wonderin. would spendin money on a new ignition system( coil packs, etc.) be worth the time and effort? i'm not lookin to blow the doors off any vettes but wanna know whats worthwhile for some extra pep in my step. thanx for the input.WM
