High rpm part time shifts with 4.10 and tune
I just got my 4.10s and a custom 93 SCT X3 tune , and Part time shifts are way to high in the RPM , leaving a light at 1/4 throttle it shifts at 3000 rpms for 1-2 and 2-3 !
WOT is great but this is going to suck for everyday driving , why would the shifts be so high ?
Could it have something to do with my J-MOD ?
thanks for helping out a Mustang Guy?
