maxing out stock 19's? upgrading?

well as most of you know my car just put down 310rwhp on the base tune, and my tuner told me that the 19lb injectors are prolly going to be maxed out, he told me to get 30's and a lighting MAF? befor i go back to him, i dont think i realy need 30's, wont 24's be more then enough with the stock MAF?

Do you ever plan on adding some sort of power adder like forced induction, or nitrous? If so, why not go with a set of 30's or even 42's? They can be tuned just as easily as a set of 19's and if or when later on you do ever need additional fuel they'll be up to the task. A set of 24's won't be good for any more than about 330-350rwhp and you'll make more than that at this point with any power adder.

i have considered a small shot of nitrous, but not to sure just yet, so 30's would be a better bet?

30's with nitrous is probably safe for up to about 360rwhp....so as long as you keep it under a 50-shot you'll be fine. Anything more than that and you'll probably start getting back up into the 80%-90% duty cycle range...and you don't want that. I'd go with 42's. Remember, when adding nitrous, or forced induction to the mix, the BSFC rate changes and an injector that would normally feed 350hp in N/A trim won't cut it when trying to keep up with a power adder. Bigger is always in the case, better. A set of 42's won't affect your idle or drivability what so ever by comparison and they cost nearly the same as 30's...so for my money, I'd go with them.

Too much injector can always be tuned around, but too little can't. ;)
