Hey guys.

Got a 13 3500 with Aisin trans just done a second gen swap with Black Market Performance s464.

Went with Anarchy Tuning.

All was fine until my CP3 pump got burnt up due to over psi at idle.

Replaced the CP3 then went with T&K tuning and now the truck is weak and won’t hold boost like it should.

The truck is in and out of gears trying to keep the boost up and it just falls on its face.

What could be the problem?
