Currently poking around in my tune file. The program loaded on the ECM right now is the tune that came from Jasper for my replacement engine which was modified for the cam that is in it. Its very weird seeing what was changed.

I need to adjust the shift points. The engine makes power to like, 6,100 rpm and the shift points several hundred rpm below that. What I also need to do is turn down the shift pressure. I don't really know what the heck I'm looking at as far as how the tables work, so what I think I'm going to do is copy the tables from the stock tune file and load them into the new tune file. The WOT shift rpm makes sense to me but the partial throttle tables kinda throw me for a loop. I need to do more research.

I just installed an ACDelco, hope it lasts 160k like the first one which actually still wasn’t leaking.

Keep in mind many a trans have been blown due to people not knowing what they’re doing with tunes.
