I just bought a predator model u7198 for an 2002 chevy silverado. This is my first programmer and know nothing but when I put the new tire size in for 20's the speedo says that i'm doing 100 when I'm only going maybe 15 to 20 miles an hour any info would be greatly appreciated
thanks.

you may want to post up what revision the tool you purchased is on, as there could be an update for it to fix any previous problems associated with it

other than that, it sounds really weird.

Soundslike a bug that was fixed in the latest revisions.

02' avalanche, have had the same problem since sept. 08, new revisions or updates will not solve problem. have had 2 custom tunes written to correct speedo and still 8mph off at 65

You could try changing your aspect ratio for the tire to see if that will fix it. This might only work though if you stay with the same size rims...
