Hello

I have Jeep tj 2006 with intake, cat back and 31 tire size

i bough inTune i like to get more hp
also, i cant change my tire size to 31, becuse i dont have it in my inTune!!

the 06 tj non rubicon models use a mechanical speedo, hence it cant be adjusted in the tunes.

it's a mechanical speedo, so you'd have to change the speedo cable gear
