$3000 later and no diagnosis

I have an 01 with an edge chip, cold air intake and 4" exhaust. I have a loss of power that feels like the truck is struggling for fuel. It seems to happen after warm up and after a good pull up a hill at constant rpms the truck will accelerate much slower than normal. I do not have a boost gauge so I am at a loss there. I am not a gearhead so I dont understand everything about the system. I have had it to the dealership , $2200 later they told me there was nothing wrong, well it did it on the way home. Another shop told me it was a fuel issue and ran it with their gauges and no problems came up. No codes, fuel pressure seems to be ok, it must be something in the turbo?

$2,200 would have replaced the VP44. At $75/hr, that 30 hours. I don't see how you could possibly "work" on a truck that long and not do anything and not find anything. I'd not let that go. That is flat out criminal.

I would start looking at:

- Do you have any codes?
- Take the Edge box off to eliminate that as a possible issue. Might just be a bad connection.
- Make sure the fuel pressure is staying at or above 10 PSI all the time.
- Make sure the MAP sensor is functioning correctly. Might just replace it. If it gives a faulty reading, the ECM may be defueling the engine thinking it is reaching max boost. The MAP sensor will connect to the Edge box, so may be related.
- Doesn't sound like a VP44 failure. This kind of failure power loss or "dead pedal" would normally throw the 0216 code, but not always.
