injection pressure too low, code p2290

How high should the desired pressure go at WOT?

Honestly "desired" isnt what you really want to look at. The key here is you only have 3000 psi WOT... It should be closer to 4000.

Are you running a tuner on the truck? Custom tunes? Some tunes can affect ICP as its displayed by scan tools.

There is a tune on the truck but not sure which one cause it was tuned before I bought it.

When I slowly push on the throttle the pressures are about the same all the way til about half way down and I see pressure of 3600-3700 and 70% on ipr. Then after half throttle when it really takes off the dsd pressure goes to 4600 and actual drops to around 3100 and ipr is 85%.

Is it possible that it is just the tune?

The new icp sensor and pigtail will be installed tomorrow. Sensor was leaking. New one came today and pigtail will be in tomorrow.

installed new icp sensor and pigtail today and no change.

would be real nice if you could return to stock and see what that does..

[04F250STROKER]

I was thinking about doing that but I wanna buy a tuner first. Any suggestions on a good tuner??

Anyone have any ideas on what may be causing this pressure issue, could it just be the tuner that was used

Sounds like a typical tuning quirk... My 2c is to return the truck to stock and go from there.

I am looking at getting a sct tuner which one should I get the sf3 or the x3? I found an x3 for $100 would that be a good one to get?
