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?
