What all would be involved in taking my Series 1 N/A and upgrading to #24 or higher injectors ? DO I have to just install them? Just wondering, thanks

just install them. the O2 will adjust them, if you go alot larger, get a ZZP afc 2.0 to calibrate the maf signal for the additonal fuel

So thats all you did when you installed yours? I really wonder what happened when the engine was cold and not listening to the o2 sensor and it unknowingly had larger injectors. I guess after a few starts and running around town it'll relearn, but just out of curiosity I wonder what happens....

it didnt take that long to relearn it. anytime you install a new performance part. its best to disconnect the battery and relearn everything

Not by itself, no. This would be done with alot of other performance upgrades, where the fuel system wasn't keeping up with engine demand.

24 seems high on an L27...unless highly modified. Maybe 21 would yield more efficient results. I'm still running stock 19'*...the mini-afc 2.0 I'm getting this week will tell me which way I wanna lean.
