recently i have noticed that my truck has had a lose of low end power, once the turbo spools at about 1500rpms the truck takes off. if im on a hill i can stall it reall easy. any idea of what it could be.

Mods- 250cc w/ 100% nozzles
ts6 chip
Striaght Piped
S&B CAI
4inch lift on 35s
 
Drive pressure leak would be my first guess. Lots of places for that to happen on a psd.

Check your map sensor line. Check turbo end play.
Making boost pressure, does it smoke more than normal?
 
get a scan gauge on it to check your icp and ipr levels. also check for boost leaks as stated. do you have custom tunes or box tunes for those inj? stock hpop? if so that could be getting weak and not giving you proper oil pressure to fire the inj.

Ill be getting a scan tool this weekend. I have a ts 6 chip from irate diesel and they set the chip up for my injectors. I am running a stock hpop

Box tunes or custom tunes shouldn't matter. It's the pressure along with other things you need to look at. You can't see 1 fault and say that's the problem on a 7.3
 
Is there a way to see if my hpop is putting out enough pressure for my my injectors to function properly
 
When i get it scanned ill get all the results and i will post them and see if u can tell me if they are good or not
 
Ok so here is everything i got from when i used the scan tool on my truck

P1670-electronic feed back not detected

Cylinder 3,4,8 contribution or balance malfunction

Map sensor- 13.35psi at idle

Injector control pressure 650psi at idle, 1450psi at 3000rpm steady

I forgot to mention before that if its below 40degrees my truck does not want to start and needs plugged in
