I must admit, those are great gains for only a tune and K&N air filter (I'm assuming stock exhaust mod doesn't help much). If these results can repeated, this tune should be selling like hot cakes.

Anyone else willing to try this???

That being said, is Frank to pushing the safety limits of the motor?
