what are the stock injector size for the 5.3 chevy 02, specs in sig....

if i upgraded them would i lose my gas milage???

what all would i need todo if i upgraded them

 

Stockers are 24.7lb. You dont need new ones yet. Wont do you any good. You will have to tune for them too. Gotta change a few things including the injector flow rates. Nest step up would be 8.1 injectors which are 33lb/hr. And theres also the 8.1 marine injectors which push 43lbs I think. One way to tell if you are maxxing the stock injectors is to check the injector duty cycles. If its at 90 or 95% its time for bigger ones. I dont think you are near that point yet.

 

because from time to time it feels a bit laggy, and so thats why i was askin
