I just had a few quick questions about my recent gear swap (3.27's to 4.10's)
1. Will a SCT xcal tuner be able to reset my speedometer calibration,or do I have to get that "Speedcal" program??
2. After the 500 mile break in period (I am at 250 miles),what kind of gear oil do you recommend? the gears are FRPP 4.10's.
3. How difficult is it to change the rear end fluid on the IRS???
thanks !
