I'll try to make this as clear as possible. I'm trying to get a list of things to check to help solve my issue.
I have a 06 LBZ, efi live idaho rob dsp5 tune, turbo back exhaust, ppe intake mod, ppe lift pump, ppe stage 5 tranny with ML converter, race valve. those are the things done that should pertain to my issue.
I ran the 1/4 mile sunday for the first time. I know that this tune should run fairly clean but the truck only puffs a little smoke off the line and then basically did not smoke the whole way down the track. Also a very similar truck that has all the same basic stuff done ran a 12.8 last year and the best i could do all day was a 13.134 @ 103. 60' was 1.9xx All this being said I think I'm lacking fuel.
Yesturday I took the day off from work to mess with it some.
I was running my pump @ 12psi @ an idle. It was dropping near 6-7lbs @ WOT, so I turned it up to 14lbs @ idle to get 8psi @ WOT. It does not lope or surge at an idle.
The fuel filter is fairly new and the in dash display reads 75% filter life left.
I have not made it to my tuner's house to check the balance rates of the injectors or the acctual vs. demanded pressure.
Any ideas on what else to check?
Thank you in advance, need to get this right so I can dyno on Saturday.
