Had a place here local that just got a dyno....so they were offering free pulls on it.
Anyways, never done such before, and took my son's stock mustang over to the place, to get a baseline before we start doing any mods to it.
It's stock '88 mustang, with exhaust bolted on. Frpp shorties, BBK X, and Magnaflow.
Last month pulling codes, I believe it was clean. New O2 sensors, new plugs, wires, cap, rotor, and coil. Timing set at 10* I believe.
Anyways, they dyno sheet showed it running lean, like 15/1 ratio. Shop guy said to maybe get a adjustable fuel pressure regulator, and run 93 octane with the timing turned up some towards 14.
So any suggestions???
