Question is do I want to spend the money on one or not? Yes or no With 37 my speedo is way off does that make a dif in performance when you get it back right again I have been told somthing about a tork converter is effected when its not calibrated properly???[/B]

 

If you have an automatic it makes a big difference. The computer still thinks you have 32" tires and has the automatic shift points adjusted for that. Changing the gear & tire size information will make a difference for autos.

For manuals, don't think is makes a difference other than having correct spedo reading.

 

THANKS FOR THE INFO
