i would like to throw this out to the tuners or those who truly know, I am sure others will be very interested as well.
let me start by saying, I love the performance of a black bear tune, but have no way to compare on my Tahoe...I have installed and driven quite regularly , a 2011 2500 truck with a tuned 6.0.
now, what I would like to know is this,
1. when reducing the TM, is it allowing less convertor slippage, or what is controlling the amount of torque to the ground ?
I recently played with a friends old SUPERCHIPS CORTEX tuner, and it did make a huge difference in the drivability in this Tahoe,
BUT, the shift timing under half or WOT situations is way off. it ran up the RPM to 5000 , felt like it quit pulling, and then shifted with a loud chirping of the tires,,,i have tried to change the SPEED / RPM of the shift point, but it only allows increases, not decreases.
2. does the black bear tune act this way, I can only hope not. all other shift seem fine, it is just the 1-2 upshift at half or more throttle.
ANY SUGGESTIONS, aside form getting black bear tunes ( I already intend to ) I am just learning the SC tuner, as to be able to help him with his truck.
