Ok what I could use is someone with a programmer that can recalibrate my tire size so the tranny shifts properly
I live in Murrieta, but can travel. Or do you think its not worth the trouble and stick with it the way it is, Im running 35" with stock gearing 3:73
Thanks

 

I do think it's worth correcting if it's off more than 5% or so. Unfortunately I don't know anyone with a programmer that can do it. The normal performance tuners cannot do it so far as I know. I thought SCT could do it, but was informed in a recent thread that they cannot.

As discussed in that thread, there is a tool called Tirepaq that does it. Anybody have one??? The programmer is $150-$200.

Then of course there is the Truespeed, but that's just an intercept module.
