what is the size of the stock fuel injectors on a 2000 5.3l

 

24#? Iirc...

 

1999 got the 19 lb/hr and the smallish 270/315 hp/torque rating.

haha, ok i was kinda close....

I thought the 2000 5.3 had 285hp?

 

It does, so 24#'rs depending on the production date I'm sure.

 

You know what, my truck was built in early 2000. I never checked when I did the 6.0 swap, but I assumed I had the 24.7 injectors. If I do indeed have the 19lb injectors would that be holding back my LQ9? Is there any way I can identify the injectors?

 

Yah you will more then likey be maxing them out with a few boltons.. No bs'n if you plan to do the LTs, cam 42's are a fast easy cheap way to go. Then you know you will have plenty injectors..

Now quit Jacking LOL

What the above stated, about your injectors, 19's or 24's

can HPtuners identify what injectors I have or my injector duty cycle if the PCM is locked?

 

no but what it can do is show u ur injector duty cycle (IDC%). That way you'll know if ur maxxing them out or not..
