When I ordered my Gryphon I got a tow tune since I tow a 4000# trailer that really bucks the wind. Initially the tune wasn't "pulling it's weight"
(I kill me), and Bill reworked the tune and now I have better response, more power, and increased gas mileage. Unbelieveable customer service!
You will be very happy with a customized tow tune from PHP. Bill most definately knows what he is doing!
