DynoJet Results

Kassel Performance 253.15 Whp and 291.12 estimated at the crank.

Epic Motorsports 248.74 Whp and 286.05 estimated at the crank.

Through the mid range the Kassel has about a 10hp gain but less above 6300 RPMs. I think with a little more time the Kassel could get to 255.00

My Takeaway is if you are racing then the Kassel is a better bet, but for the street the Epic is less stress on the engine.

List of Modifications:
  • Headers
  • Straight pipe exhaust to Supersprint Muffler
  • Dinan larger throttle Body
  • AFE Cold Air intake
Is there any chance the AFR charts are reversed for the two tunes?

One goes pig rich at the top, almost looks like cat protect is not turned off. You would expect that tune to produce the least amount of power in that range.
