Injection control pressure?..

[case340]

When I get the urge to go flying around backroads and mud pits and whatnot in my truck, every time I get on it it throws a code 1211? I think? And it says injection control pressure maximum/minimum exceeded or somethin like that... is it just not getting enough fuel or what? It's a 2000 f250

Oh AND the dang turbo only builds 15 pounds of boost.. what gives?? My obs with its stock turbo which I think is smaller than the turbo on a newer 7.3 builds 28

What mods do you have done to your truck?

What tuner, injectors, or any other mods?

How many miles?

OBS has a larger exhaust housing, which makes for less drive pressures and lower boost, however it does not have an intercooler which leads to higher boost, but hotter air...

Superduty has a smaller exhaust housing, but a wastegate. This allows for it to act like a small housing at low RPM's for better spool, but at high RPM's it will act like a larger housing... It is also intercooled, which lowers boost levels and gives you cooler denser air.

Need to know your mods to tell you anything...

Sure it is... wait... How is it that you know that?

Could be a bad ICP sensor, bad injector O rings, bad or leaking IPR... Could be over agressive tuning...

Could be anything.

Get some facts before you throw out statements.

It's stock besides straight pipe, and edge evolution cs. And its not the ipr leaking I was in that area of the motor just recently, no leaking of any sort besides an engine oil leak lol

with a programmer/chip it very well may be the tune calling for too much oil and the pump not being able to keep up

Need to data log and see whats going on... Watch ICP pressures and duty cycles.

Icp is always moving around it never stays at a set psi say like at 70 its fluctuating. Is that bad? I think it got up to around 2500 psi tops

Whats the %...2500 psi is normal for a stock truck..that said any good tune and stock split shot inj's will tax the 17* HPOP...SRP1.1 will cure that problem.
