Do I have to remove the tune and then reapply with the new parameters or can I adjust independently. Also I notice u have 93 tune. How does it compare to the 91? I'm running 94octane anywayHey, sorry I'm a little late on the thread, but if I'm not mistaken on my DSP it's under the "adjust parameters". Let me know if I'm wrong and I'll go and plug mine in to be sure.
I didnt notice much of a difference in perfomance untill i really beat on it, from 3500-6000 rpm you will notice the extra power. as far as the transmission tune you should notice faster and more firm shifts as well as the shift points are adjusted, if you go into the options category in the dsp there is a "last tune writen" tab that will show you the current tune. then you will know for sure you did it correctly.I uploaded the DSP 91 tune a few days ago, and for some reason I really cant tell a difference in performance of the truck. And the mileage is about the same..Did I do something wrong?
What is the difference with the stock vs. Performance transmission settings?
