46re Odd Shifts

I use HP tuners on my Chevy and it’s extremely complicated. Lots of variables. If I need to make changes to a shift strategy or shift timing, the truck goes to a tuner. It’s beyond my scope of understanding at this point. I spoke with Ryan a year ago or so when he did my tune, and he was in Florida at the time. Might be different now. But I can’t stress it enough that playing with the tune on a trans can go bad very quickly if you’re not well versed. I know HP tuners now supports jtech (finally) but I would still contact Ryan. Like I said, wizzard.
