4.8 injectors?
ok, I searched, I tried performancetruck.net and I googled it.....
What is the rating on the 2004 4.8 truck injector?
It appears the 6.0 is a 24.8 lb per hr injector, what about the 4.8

2003-04 Express, Trailblazer 5.3
2003-04 Envoy, Savanna 5.3
2003-04 Express 4.8
2003-04 Savanna 4.8
2002-04 Denali 6.0
2003-04 Express, Silverado 6.0
2003-04 Savanna 6.0
2002-04 Alvalanche 5.3
2001-04 Silverado, Suburban, Tahoe 5.3 (T)
2001-04 Sierra, Yukon 5.3 (T)
2001-04 Silverado, Tahoe 4.8 (V)
2001-04 Sierra, Yukon 4.8 (V)
2001-04 Silverado, Suburban 6.0
2001-04 Sierra, Yukon, Denali 6.0
2004 SSR 5.3
2004 Envoy 5.3
2001-03 Silverado HD 6.0
2001-03 Sierra 1500 HD 6.0
2001-03 Silverado 2500 5.3
SO I WOULD SAY ITS IN THE PCM AND FUEL PRESSURE THAT CHANGES THE CHARACTERISTICS IN DIFFERENT VEHICLES USING THE 3 DIFFERENT ENGINES

The software I use for tuning showed that my 2003 had 25.24 lbs/hr injectors. Are you looking for 40-60 lbs/hr injector at 3 bar(43.5 PSI) or 4 bar(58 PSI) fuel pressure? The ones I had made were 63.4 lbs/hr @ 43.5 PSI and 73.2 @ 58 PSI. The 8.1L Marine injectors flow 37.95 lbs/hr @ 43.5 PSI and 43.8 @ 58.
What mods do you have?
Here is a link to the ones I had made.

You can get the 8.1 Marine units here:

*Not sure if it's ok to post their link but will remove if needed
