Guys I been playing around into making this tuck to shift right 2nd and 3rd, The truck its making good power turbo 5.3, have run high 11's letting go the gas pedal to shift 2nd and 3rd.
I use the bluecat tool and haven't got any luck, Ive use it on other vehicles and work pretty good just not on this truck. I'm running 29.5 slicks on the back and her stock 3.42.
I'm running the 29.5 tires and they are calibrate for the tire size and the abs, brake and traction control light comes on, and if I don't change the tires sizes at high speed the traction control kicks in and it brakes the truck hard at any time and I have the TCS off on the file. I been play with torque management, shift points, pressure and nothing can make it shift.
Any input on what else can I do? tranny its running a 3600 triple disk yank. Motor 5.3 on 13 lbs, stage 2 btr boost cam.
