I have a 1987 mustang gt. Its a speed density set up, 5 speed. My upgrades include CAI, 70mm tb, bb@k long tube headers, off road h pipe, underdrive pulleys, upper and lower cobra intake, msd coil, 4:10 gears.
My question is, will the jet module chip help or even work with my speed density? I'm not looking to make my car a drag car just a weekend joy ride!
