haha thats what i said when he told me that

 

Gonna wait for my Travel claim... then... Time for 60lbs... Thank you USMC!!!

 

sorry to interupt but does anyone know what size the 6.0 injectors are...

 

With your truck being only a 5.3L and being a returnless system you may be close. At 15psi your fuel pressure should be around 75psi. That is going to be a big help. Shift rpm would probably be a big point in the issue of if they are big enough, especially with that cam. I'd be more concerned about the tuning....

 

I believe you ment return fuel system, good luck seeing that pressure on a returnless.

 

42's are not gonna do it

 

ok...so is it or isn't it? on a return system being the op's truck is an 01. How far can the 42lbs go on a return system?

 

Here is a reference, on my 4.8 with 210/218 .551 lift cam, I made 505 rwhp spinning it to 6200 with 43's and a M15 meth nozzle squirting -20* WWF. Injector Duty cycle was 105% and aft was about 11.3. Boost was 11psi and my truck is a return style fuel regulator.

 

I got my Siemens Decka 60s from BlownChevy for 275 shipped... Spaced the rails and swapped plugs and was done... It was an easy swap really.

 

LOL, yeah. Thanks. Return system is what I meant.
