Lift pump pressure

[J17HENRY]

My lift pump pressure falls to around 3 psi under full throttle. Is this a problem? If so what can be done to get it higher, have a airdog 150.

Probably need a bigger pump

It's nothing to worry about. As long as it keeps positive pressure, you won't notice any performance loss.

I think that is good pressure given the mods in your sig. Thats on the verge of needing a 220.

Is rail pressure falling off?

Not to derail but whats people running with 100% overs and dual cp3's on a bigger tune say 2800us.
