Someone may have to help me a little here...so when I went to 87 tow (truck currently in 87 tow) and selected yes on custom tunes, I then went down to load previous settings. When I scroll through to check the settings, all of the shift point speeds are at 0??? Also, the tire size reads 2356 which is way off for 275/55-20 tires. Oddly enough, my speed is accurate with the GPS. If I put in the circumference of tires with 5% squish, my speed is about 2mph faster than GPS at 55mph.
Is there a way to see current settings loaded on the unit with 87 tow mode? I can't seem to get the "load previous settings" to load anything for me to view.
As I'm typing this, I'm thinking to myself "My truck runs great; I can't wait for my custom tunes; Why am I tinkering with this?" Oh well, guess it's part of my figure-it-out nature. Don't anyone lose any sleep or family time over this. I guess we're just tinkering around.
Merry Christmas
