2005 Silverado Speedometer issues

[jacobh]

i have a 2005 chevy silverado and a diable intune, it had a custom tune built when i bought the truck along with the tuner and when i tried to reload the tune my speedometer is off and abs lights flashing. the truck has 4.56 gears and 35/12.50/20 tires on it, would anybody be able to help me fix my tune or build a new one? i also have the cats removed is there anyway to make any changes for that in my tune?

[mikel]

did you use the tuner to adjust for the gear and tire size changes?

[jacobh]

i dont see any options to change the gears, and i did try to put it the tires by size and actual tire height, and it was still off by 15 mph on both settings, where can i change the gears?

[mikel]

if the axle ratio setting is not there, please post the backup and last tune written file from the intune drive and we'll set it up for you.

Thanks
