LBZ: New best.....

[Devon]

So I've Been battling my p0087 low fuel rail pressure code,well I ran my truck tonight with the suspected worn out cp3, and managed a [email protected] with a 1.75 60ft. Hitting the end of the track with only 19,100 psi of rail pressure and a desired 26,100 psi... I belive I need a cp3 and quick. I am losing mph and e/t!!! I'm sure the trucks good for a 12.6-12.7 no problem with a good cp3

R u still running ur stock filter? Maybe try drilling out the fuel rail fitting before digging into the cp3. Just suggestions. Hope u get it figured out. Iirc u have the gray excab and that truck is bad ass. Hope it goes some 60's or 70's for ya

Yea this has been killing me, I don't know, but whatever it is, it's crapping out fast, just over a month ago I ran when the track first opened and trapped 103.5, now I can't even trap over 100...oh, I'm not running the stock fuel filter anymore if that's what your talking about

Did you drill out your fittings in the rail? Try turning your airdog up in pressure to.... what's your pulse width on your race tune?
