Ok, so after the full rebuild of my engine I am getting a few DTC codes relevant to the HP turbo. They are as follows:
P2263
P2563
I have replaced the EBP and MAP sensors with no help (although it seemed better for a day or so after the EBP was swapped)
EBP tube is clean and clear, VGT actuator moves freely.
Truck is sometimes laggy and smokey off idle, but sometimes makes 25+psi with only light throttle (overboost condition).
Just today a P0472 showed up...I was watching back pressure on my MiniMax and it was 0 at idle a couple times but seemed to respond instantly to throttle input.
I have a VGT actuator on order, as even though it moves freely I originally thought this was the root of the problem. It seems to cycle funny at key on so I thought I would try that.
HP turbo passes a little oil on the compressor side, so I will pull it and rebuild it shortly - I don't think its bad enough to limit performance though.
Looking for thoughts and opinions please
