For all you problem solvers out there.... could really use your help on this one...
So a brief history, almost 2 years ago I bought my 95 F 350 psd with approx 150,000 miles, and always ran “ok”. My plan for the truck was to build it up to make good reliable power for years to come. So over a couple months time I upgraded to:
Baby Swamps
Dieselsite wicked ball bearing turbo
Adrenaline HPOP
E-Fuel
Hydra Chip
K&N filter with banks intercooler and 3” downpipe
Gauges and ect
After these upgrades, truck ran absolutely amazing. All tunes worked perfect, making great low end/high end power, very responsive to throttle, and egts way way down.
As you could imagine, it was easy to put the pedal to the floor whenever an opportunity presented itself, which quickly gave me my first problem. I’m no mechanic, but thanks to you guys and these forums, I bought myself an AE scanner and found I over boosted the truck causing it to defuel. Cleared the code and problem solved. Happened a couple more times with no issues after clearing the code.
My current symptoms:
Truck is running like it did with the overboost code, but there isn’t one stored anymore;
Truck starts but takes a couple seconds longer than normal, runs slightly rougher at idle, NO low end power when trying to accelerate @1500-2000 rpms with heavy black smoke, good high rpm power however not what it was.
Boost gauge still registers same numbers, and no significant boost leaks found.
With my AE, I get codes P0478 and P1211 after WOT run.
Also at WOT, my EBP gets to 50psi, ICP tops out at 2460 and oddly holds there, and ICP duty cycle tops at 35%, with MAP reading up to 40psi.
All these upgrades were done less than 6 months ago. I’ve done all the KOEO and KOER tests with the AE tool with no significant findings.
With all these symptoms, was curious if anyone had a direction I could head to figure this out. I’ve spent a great deal of time in my comfort zone, which is behind the computer searching these forums for solutions, but haven’t got one.
Thank you all in advance and I know I probably said something dumb too so I apologize for that in advance as well!
