My brother has a 1320. He purchased a new OEM PCM . They put bigger injectors, E85 tune, light wheels and tires, smaller crank pulley. Made a huge difference. It's been 11.00 @ 125 in the 1/4 in really good air. I think it weighs over 4300 lbs with him in it.

Nothing worth anything comes easy. It is always harder to do the right thing. My Grandfather
