So the car I just picked up has a Mustang GT axle swapped in for the IRS...with the stock 3.27 gears. Verified with GPS etc. Speedometer was correct so the tune has the right ratio in it.
1st goes to almost 60mph what the flying ****
Do I want to spend the money to do 3.73's? Should I just wait and do 31 spline axles and the whole package down the line?
