You have something pulling a lot of timing and fuel, I would look over your timing correction tables and turn off torque management.

Dont throw parts at it just yet. Its a dual CP3 truck... you need to adjust the fuel control parameters to straighten out the rail pressure, it's not going to just automatically work right when you double the amount of available fuel.

Thanks for the heads up. I would have figured ATS would mention this in their kit if that was an issue.
I'll do some searching in a bit to find a write up on how to lower idle rail pressure.
As long as he hasn't messed with the FCA amperage it should work fine. 22k psi at idle while the ECM is asking for 7k is not a tuning problem.Originally Posted by Turbo_Mike
Rail pressure fixed. I forget these kits have the duramax FCA that only likes 10-12 psi. Adjusted the pressure to those and rail pressure dropped and idle is quiet
Any improvement here after correcting the fuel supply pressure issue?

You need to go do a 4wd launch WOT until about 100mph. When you are on and off the throttle its hard to tell if everything is doing what it is supposed to.
