Does anyone still have this? I have the really old Pred. and I lost my copy of the gear ratio to tire size breakout that I need to calibrate the speedo after a gear change. Yes, I already searched for about an hour and couldn't find it anywhere. Thanks guys.

I still have it, here are the M6 sizes:
3.42 to 3.73 - F: 275/40-17 A: 235/30-16
3.42 to 3.90 - F: 275/40-17 A: 235/35-16
3.42 to 4.10 - F: 275/40-17 A: 235/40-14
The chart I downloaded from diablosport in '03 says 235/30-16 for 3.42 to 3.73? Use www.f-body.org/gears/ to verify after making the change.

save the custom tune to your PC....
you should be able to read the current tune outta your car, then export it from the predator to your pc...
the instructions and necessary application should be on the download/support page at diablosport's site for your model predator.
either way, when you send it in to get updated, you're gonna have to be runnin' stock while it's shipped out...
but then when you get it back, you can just import your custom tune back into the predator and reinstall it to your car...
