hey Kyle I live in Autsin just a couple hours drive from woodlands im working on piecing together a turbo build for a 4.8 I will PM you.

 

Sounds good!

 

You will need 38 lbs at a min and 255 pump...

 

Would the same size apply for a 4.8?

 

i agree on higher boost i´ll need bigger injectors and pump but dont you think i´ll be fine running 5psi with stock ones? i attached an hp tuner log with the setup i have now (6.0 bolt ons and cam) im here to learn so correct me if im wrong, injector duties isnt maxed out at all now is it?

 

If you insist on running stock injectors with a 6L on boost, then you better limit you boost to about 4lbs and no more then 4000rpm... But why risk that much money and work over a set of $250 injectors??? Personally, I think it's foolish...

I don't have HPT on this comp, but I'll look at you log when I get to the shop.

 

Your injectors are currently at 81% dc and your shifting ant 66-6700 rpm! You put any boost to that at all any your gonna max them injectors out and your motors gonna say I hate you and good buy!! lol

5lbs of boost is about 1/3 more air, which means you gonna need about 40%+ more fuel since FI need to be richer then NA. That's gonna put you well over 100% DC on those injectors.

 

don't get me wrong man! i understand and of course i´ll change injectors its just that couple of times i sow people with similar combos as mine maxing out the injectors and i sow mine where at 81% i tough i was getting away with 5% but i see i don't, thank you for explaining
