I turned the TM back on and this appears to have taken care of the quick/slamming 1-2 shifting at low speed. I was really worried about this hard shifting when I'm tow in tow mode. I'm not sure as of yet if this enough.
Question, could you explain what the partial throttle firmness adjustment is for? I assume it is to adjust how firm the tranny shifts at a partial or very slow speed. If so I might need to try reducing the firmness there later if need be as at low speed is where it shifts so hard. I'm running the canned 87 tune and love it. I bought my Predator in 2003 and sent it in for the upgrade several yrs back but have never upgraded to the present Ver.
I can't speak for every vehicle out there, but as for fuel mileage and power I love the diablo and 87 canned tunes in my pickup. I KNOW what my mileage is because I've calculated every tank since I purchased this truck new! Last year I lost the tranny at 46K miles due to a faulty sprag which chevy wouldn't stand behind due to the age of my truck. I had the tranny rebuilt and during that time I had removed the 87 tune. I noticed that fuel mileage was running in the low 16's and just recently installed the tune and dialed in my fuel trims, and guess what? First tank of BP 87 on 371 miles half tank interstate half tank VA mountain calculated 17.47 MPG AVG! I KNOW I get better mileage and power with you tunes!
