Ok here what goin on. Truck is turned to stock on everything has 150 injectors intake and exhaust. Stock lift pump stage 2 cp3. On an up hill I can't hold more than 4k of rp. Lift pump going or connector tubes on an injector it self?

It will stay around 14k rp light peddle flat or down hill

Thanks

I hope you didnt burn that cp3 up. I know with my stock lift pump it would only hold 8psi at idle and when my smarty was set on kill I could draw it down to 0psi. With your programmer, 150hp sticks and stg 2, I know its starving to death for fuel. Dang man, I would have done the lift pump before everything.

Well made it home. I ordered a new lift pump summit has an in tank replacement good for 600hp so we see how that works. Looks like an air dog soon too.
