I have a 1lw that is an absolute dog . Makes 60 psi of fuel pressure at idle and about 80 under load while driving. New turbo non waste gated . Makes 30 psi of boost but it doesn’t pull well. Also please note the truck has about 80,000 on the in frame . I’m at a loss now . The fuel mileage is horrendous . File number in the Ecm is 1708226 .
