It's still doin good , I pulled the fuse out for the turbo and ran it for a while made it run a lot better and it helped the fuel mileage but you lose the exhaust brake changes the way the truck sounds to and the tranny seems to shift better im guessing because the mass air flow sensor and the TTVA motor (throttle body) get there power from the same circuit as the turbo and unplugging the 2 sensors dont give the same results as pulling the fuse so im going to run a fused wire from the fuse box over to the turbo and cut the power wire and hook my wire to it and see how that works
