it's a 99 5.3. Full bolt ons, camed, tuned, built tranny and stall.

I remember hearing the the 99s had really small injectors, and I want to make sure thats not holding me back.

so if you could tell me, or tell me how to find out it would much appreciated

thanks

It is. I was at 97% IDC with just a cam intake and an exhaust. They have 19 or 21# injectors. Some people will say 1 others will say the other. My tune files all say 21#s though.

 

so you were maxed out with the 21#s huh. i wish injectors were cheaper.

 

08 6.0 injectors. size, plug and play?

 

how much bigger are the 00-07 injectors?

 

I believe that they're about 24.7 lb/hr...

not sure if the 08 is plug and play or not though...

 

Check ebay man. I paid $24 for my 31#ers, $185 for my 42#ers and $180 for my 60#ers with spacers.

I just got a set of '08 8.1L injectors (with fuel rail ) for $100. Got them yesterday and they are 100% identical to my old ones. I'm using these on a 440hp LS6, which is just big enough.
