Do you know if Forscan lite will be capable of doing a speedo recal
Bora 2inch spacers?
forscan lite wont do it. You will need forscan on a laptop or desktop to change the speedo. Its done through editing the tires revolutions per mile number on the abs module. You also have to register on the forscan forum and request the temporary extended license. Forscan wont be able to access the abs module without it.
If you care though... I did it and went back. I got the new tire size revs per mile from the factory. for my 285/75r16 bfg ko2s at tires I edited the number and put the pcm in relearn. It really messed up the shifting esp when towing. it kept shifting up sooner dragging me out of the power band. my speedo was spot on though hahaha. I even experimented with a number in between the old and new revs per mile number and it improved but barley. I ended up going back to stock size.
You speed will barley be off. when I was going 67 mph I was at 69-70mph (it fluctuated back n foiurth) using multiple gps types to verify accuracy.
Also you will want to buy the $2-400 hub centric spacers. if not you're going to have big issues esp towing. these trucks use hub centric wheels not the normal kind. 1.5-2in spacers will be expensive and still require you to check and re-torq them often. I would just find a set of 18in wheels for the backspacing on the 99-04 trucks and save the hassel personally.
