Fuel Pressure

[CLAYTON]

How does the truck respond when your fuel pressure is down at 0 psi at WOT? Does it just hesitate a little but keep going? Is it really hard on the pusher pump?

They can buck a bit, or you might not even notice it. The more mods you have, the more you do though. It's hard on the VP44, not the lift pump. Anything less than about 6psi is something you should work on.

What about CP3s in the third gens?

 

[KLockliear]

Typically, acts more like a miss on a CP3.

 

[CLAYTON]

What does the CP3 do exactly?

 

[KLockliear]

The CP3 is your high pressure injection pump.

I've been feeling a sort of bump/miss since the twins have been on. Fuel pressure is reading no less than 8 psi. I don't feel it when I'm in the throttle hard, its when I'm letting off of it is when I notice it. Anyone have any ideas on what it could be?
