Tcm support will be ready april 1st....

try and roll out the actual diameter use that instead of a sidewall number or standing diameter, since I've done that no lights going on a month and close to 3500 miles. Very frustrating I know but my truck was extremely picky on what it would take

It's a Christmas MIRACLE!!! Bought a new set of tires for the truck (275-65-r18 Michelins) and thought let me try this crazy predator one more time ... ended up measuring the circumference of the tire calculating the diameter off of that (it came out to 32.12) stuck a 32 in on the tire size, set the ...

another monday of driving without my predator...

back to the top....

back to the top to start another week...

yup I know the feeling I have another thread that one of the tech guys had me post original backup and last tune written but havent heard anything, and I havent heard any thing from the first diablo guy who sent me a tune to try a couple of months ago.

ok I've got 265/65/18's and cant get anything anywhere near that to work

Was having the same issue, but when i manually inputted my trucks tire sizes with the tune it fixed the problem for me, did it a week ago and light hasnt been on since. Wasn't sure if you'd tried this yet.

what size did you put in and what size is stock on your truck? seriously cant get this to ...
