the highest my truck has ever hit is 42 psi with all the mods in my signature. would def. recommend getting a nice aftermarket lift pump like a fass or air dog or dragon fire before getting a programmer. try and get one that comes with the upgraded larger diameter fuel line to feed the vp44. then get a programmer. that way you wont starve your vp44 of fuel causing it to eventually fail.

It's a little more involved to block that wastegate off, as it is a steel tube compared to a hose. When I plugged mine, I pulled the tube off and threaded a machine screw into the tube inlet with red loc-tite on it. After that set up, I ground the head off with the bench grinder. Reinstalled everything, and went from 26PSI to 34PSI.
