hey z boy, when you evolve to a bigblock look me up, i'll run circles around you now! it wasn't understanding how to use it,it would not adjust my speedo!look up my old post.

I got my predator in sept. 08,would not correct speedo, after 6 months of aggravation (website discusion, custom tunes, tech line,etc.),still not resolved. The store i purchased at has a 1 year satisfaction policy, i sent it back in exchange for a superchips cortex, got it last week & it is far ...

no change with new tune , speedo says 65, gps says 73-74

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

reset paremeters on tune & reinstalled with no mods,at 55mph on speedo gps says 61mph

installed tune & no help, i can moddify sidewall #, or tire height , load tune & speedo sweeps when i go into gear ,start to roll & the speedo pegs.

here's original backup

here is my last tune ,02 2500 avalanche,8.1,4x4,4.10 gears,325-50-20 tires,u7198,9r09, THANK YOU
