Sorry 14500 psi

We need a lot more info. Is the truck tuned? Are there any codes? Has it always done this or is it new? Have you replaced anything lately?

Lack of maintenance, poor fuel, worn parts, bad tuning.

We can be just as general, you gotta feed us FAR more info. All we get to go off is your text which can make situations like this difficult to figure out. We know alot but we dont hold crystal balls
