if he put 24# injectors and didn't change the MAF, thats the baseline of your problems right there. either downgrade injectors or upgrade MAF.

i asked a few mechanics if they could be screwing anything up and they said no they should just be running like a 19lb injector would. i think tomorrow night im going to put the 19lb one's back in. if nothing else it'll be better on fuel.
