I see 265 tires in your sig
Have you recalibrated your vssb for the larger than stock dia tire, or? Your 4.10 rear ratio is now taller by the difference in dia of tire meaning you are going faster that speedo says if not recaled..OD and lockup is now slightly higher too.....
I run 3.42's w/33" dia tires and that gives me really tall gears under all situations. I can drive in 3rd only and get lockup @58+ mph w/same rpms as if I was running stock sized tires and 4.10's I do this up to say 62mph w/o issues.
