Has anbody figured out if we can dealer recalibrate for 35's on the '06 models?

 

so far the only recalibration I have seen is if you are lucky enough that your tires are listed in the ECM.......my Nitto 295's were not listed and we picked a close one but it is not the right size. I think you could pick another size with a different size, ratio and wheel and get it to work out.....but not through dealer so far and they have tried twice on my truck with me watching.

They say the Smarty and/or Superchip will let you recalibrate.......but not bought one to try it and have not heard anyone talking about it....

Good luck...

 

They told me they got it as close as they could and I checked it on the freeway the other day speedo @ 65 with cruise on and the radar sign read 69-70 Dont know how close to consider this close butoh well not much I can do .
runnin H2 take offs 315 70 17

 

My Super chip flashpaq did mine , it goes by inches.

 

When you change the tire size with the Superchips does it change the size by inches (33,34,35,ect.) or can you do fractions (32.8,32.9.33.00,33.1,ect.)?
