[dirtdriver11]

Looking to replace the injectors in my 2008 Sierra with the 6.0l. I found some that are aupposed to be an upgraded version with 4 holes instead of 2 and are 310cc. I can’t find any information about these. Anybody have any idea if these truely have any upgrades over the original?

You wouldnt want to go any higher than a 144lb/hr at 43.5psi (most people would say 145/44) without getting some kind of tune and upgraded internal engine components. It really is what you're looking at doing with it.  If you're looking for just a better injector. Go with a Delphi reman 4 hole injector. https://amzn.to/2Oeaj23

But if you're looking for performance. A set of AUS 124lb/hr at 43.5 or if you want to push it go with a 144/43.5

Not looking and doing any performance upgrades, just wanting to replace injectors. The truck is completly stock other than doing away with afm before I bought it. I

 

I went ahead and just ordered a set of 2 hole reman injectors.
