I am still trying to get my tune issue worked out if nelson would ever call me back, left three messages already. Well anyway, when I am driving the truck at lets say, 1/2 throttle, and when it pulls 7lbs, when it gos to shift from 1st to 2nd, and 2nd to 3rd, it sounds like the truck is hitting the rev limiter or something. It just acts like it doesnt want to change gears. Driving the truck normal with no boost it shifts fine. Any ideas?? And another thing is when I am coming to a stop or slowing down to near stopping, the truck acts like its wants to shut off, kinda bogs down for a couple of seconds then it idols fine. The idol is set at 800, please help thanx nick
