So just got done installing my new motor and was hoping the boost issue I had the last time I started the truck before I tore it down was something wrong with the motor but It’s still not building boost. I did put a scanner on it and got code p2262 and p2263 which is a turbo performance failure... I did try another MAP sensor and it made no difference and the EBP sensor is working fine... I split the turbos and replace the gaskets between them and the seals that go through the elbow and small pipe under the fuel cooler.... the turbos seemed fine and spun freely and had now slop to them but I’m wondering if there is something wrong with the secondary precision turbo set up I have on it... any help with this issue would be great.
This is the set up I have. ![]() Sent from my iPhone using Tapatalk Pro |

You got the fire ring on the wastegate??

Is your vgt actuator plugged in? Does it do a full sweep when the key is cycled?
Could always remove the waste gate entirely to eliminate the possibility. |

Yes the vgt is plugged in and moves as it should.... the truck did this the last time I started it before I pulled the engine for the rebuild. Sent from my iPhone using Tapatalk Pro |

So I took the dump pipe off the wastegate last night and no pressure is coming out so that rules out the secondary wastegate issue... so what’s next? I pulled out the ebp sensor and the tube both were clean... cheacked the map sensor again everything is good there... is it possible these turbos are junk?

But I would do a boost leak test on that truck before digging any further. |

It’s not that I’m leaking boost it’s the turbos aren’t even operating and are even trying to spool up Sent from my iPhone using Tapatalk Pro |
