Tuned on the Dyno this morning. Very nice way to tune. Especially since where I live, I'd have to take a 10 min. drive just to get somewhere I could run the car above 30mph. Hot and humid, but I pulled 300 HP / 390 lb/ft at the rear wheels. Use a Mustang Dyno. I've always heard you lose 20% for the drive train. In my case a bit more, but this time I didn't have headers (LB manifolds instead), and I had a clutch fan vice electric water pump. Car has great seat of the pants, we'll see how she does when I fuel inject it in a couple of years.
