Dan that is good stuff -
I recently dynoed mine and pulled 433/397, on the stock pulley & tune. (FM catback and Pauls HP airbox only) I am interested in the predator, to lean out my a/f. It drops under 10:1 at 4200. real bad. and I know I can pick up alot torque with a tune, but i dont want a chip
Anyway I am trying to learn more about it.
Peace
