Just grab some 90-120lb injectors, either of these would have no problem getting you 700-800fwhp, on e85 or 93.... And when looking at injectors keep in mind that most all companies rate injector flow at 3bar, and Gm fuel pressure runs at 4bar... Basically means a 80lb @ 3bar rated injector from Bosch is going to be a 90lbish injector when you put it in your Gm truck which runs @ 4bar.

 

Stock form a gmt900 commands 43.5 for normal driving

 

90-120# injectors will get you 700-800fwhp on e85 or 91-93 octane, @3bar or 4bar....

 

as stated 1300 for 900rwhp if using e85

 

As "renright83" stated.... Not looking for 900rwhp, he's looking for 700-800fwhp...

As stated go to fuel injector connection. fantastic company, they will take care of you. let them know your intentions and you will get outfitted with what you need. I have ordered multiple sets for different vehicles from them zero problems.
