gear/tire size change

[Brandon B]

I have a 1999 Chevy Suburban I lifted and put 33" tires

hooked hp tuner went to edit and gear/tire wizard, when I look at what is already programmed in its not a tire size 0.70 with 3.42 gear

I input my tire size 33.1 and the rear gear 3.42 and hit adjust and it now shows tire size is 1.08 with gear 3.42

I see videos with people doing the same thing and the tire size is correct on theirs. is it because 99 model or am i doing something wrong?

Thanks in advance

are the units of measure correct? also a better option is using the bluecat trans tool, by far the best way to feel a HUGE difference

Are you sure you are not reading the multiplier? As to bluecat it is great but you still have to do the tire wizard first. Post your tune.
