Fwiw warranty goes off build date not sure why but that's what i got told by gm but at least your injectors are easy to swap and can do just one not a set
LMM: trucks falls on its face
- Thread starter KEVINL
- Start date
Could be a weak pump shit happens, id try shimming the valve or maybe drilling tge rail fitting?? A log would be best though and if you do a lift pump think of it as safety for the injectors! I have alot of people who just put a fass on for the filtration and peace of mind
Well i dont think no amount of hard part fixes would have fixed his problem. balance rates are great, holds 160mPa at idle buuuuuuuut
Its definitly not a stock tune lol. someone tried to tune his truck before he bought it from what i can see and they didnt do a very good job. under WOT, it starts to drain rail and hang the shift. the more it drains the rail, the higher the PW goes. i have a log of it hitting over 4000uS with 5,000psi of rail pressure hanging the shift before 4th gear. at 95% throttle she runs perfect and holds awesome rail.

If it is draining the rail that much, pulse should go up that high. Look at tge pulse table and you will see it in the bottom left corner.
My truck would do this when it was stock with a dirty fuel filter. Need a vac gauge to test at the factory fuel port.
Fuel filter is new
Where can I get a vacuum gauge that will hook to the test port
I am not sure. Maddmatt had the one I used before. It was digital and would record max and min. It wasn't a normal gauge, it was a square tool like piece.
ah didnt know that! The tune that is in it is the one that was in it when he bought it. its not a stock tune by any means, the trail of black smoke out the tailpipe with a DPF still in place agrees with me lol.
his truck will hold 26k at 95%+ throttle till he hits WOT, then its game over. You might try a bottle test kevin and see if you get any fuel from the FPRV comin out. I still dont like the tune in it, it carrys a VERY high PW from the bottom left all the way up to 140mPa so as soon as PW starts to drop, PW starts sky rocketing quickly.
If you can have Steve look at the tune and give me his feed back. I may need to do the bottle test and check the vacuum at the gauge port but I want to eliminate the tune
I am real close to giving the truck to the wife and taking her car :roflmao:
