I loaded the file that Rawze so nicely updated and fixed up for me. As soon as I started the truck it was noticeable that there were changes made. At low idle 750rpm the truck idles smooth Turbo 54% closed compared to 72% closed. Test driving around the truck seems to run nice Intake manifold and exhaust gas pressures are both lower then compaired to before. Had about 34psi boost trying to load engine up a hill on test drive. The real test will be once I get it out with a load again. I pressure tested the intake system starting at the CAC did not have the correct fittings to start at turbo, tightened couple turbo boot clamps but didn't find any big leaks. Very interested to see if my poor MPG improves 2mpg before.
