Low ICP? and P1211 code

For a minimal fee, I'll send you a good pair of valve cover gaskets and under-cover harness.

The connectors melted due to high resistance, either from oil intrusion or a loss of terminal tension.

I wouldn't splice those......

The dealer has what you need. It's not "cheap" but you won't have to worry about it happening again.

Mahaloz guys, I already payed the dealer

Got every thing back buttoned up, But Im still having BOOST issues !

Manifolds or should I say headers, are good, uppipes so far so good..
biggest mess I notice is the damn CCV leaking , Need to figure something out with that..
but I don't know where to begin to look now, Most the intercooler boots that I can access are pretty darn tight, I notice a little oil residue inside also from the CCV i guess ?

How can one test for boost leaks other wise? I've read about caping the intake side of the turbo and pressurizing the system? but still a bit confuse on that..

I googled it for you and the first hit was over at PSN in a thread you started today....HA HA. Looks like you'll get an answer over there.

LOL I know..And the best part is, turned out I have no Leak, but a sticky waste gate on my new SD turbo

I assume its OK to run without the red tube connected to turbo? I was told to unplug and see if I still had turbo problems, and Bam! 26lbs of booosstt
which seems fair for my AD codes yeah ??

and also no more CEL, Did get a new set of tunes from Bill, with Upped ICP and timing, But I could set the CEL(not knowing what code) last night no problem,
but with the "red tube" removed from the turbo it runs fine, no CEL

can that be related ??

One benefit of having a GPCM not a GPR is it will throw a code if a glow plug starts to draw too much or not enough current. though when the GPCM goes kaput they are about $150 to replace... been there, done that!

It probably has something to do with your older truck not having any means of control for the wastegate (since those trucks didn't have one). If you hooked the red line directly to the manifold (seeing boost pressure all the time), it will start to open the wastegate as soon as any boost is produced. The Super Duty trucks have a solenoid valve that inhibits any boost pressure from acting on the wastegate actuator until a certain boost level is hit under certain operating conditions.

but with the "red tube" removed from the turbo it runs fine, no CEL

can that be related ?? The OBS trucks do not defuel under high boost conditions, but they will set an overboost code. My guess is that you are setting a low injection control pressure code.

Hope this helps. Good luck!
