I first got my Evolution programmer(11/04) that has Bill's programs. Power and driveablility are good in all programs. Smoke's like a freight train in extreme and is manageble in the 80hp tune. 60's no problem.
Next I got a TS chip(2/05). Had Fuel 7, 125,100,75,50 and stock programs. Smoke was crazy in 125 and F7, 100 down wasn't bad. The hotter programs were too noisy and rough for me. But Dennis has gone through the 7.3 programs since then.
Now my chip has DI smokeless programs(3/05). Power's great and smoke is minimal, it is a tenth or two slower at the track then my Evo. I still have to make it to Houston to let David play with it.
The Evo has yielded me the best MPG in the 80hp tune. DI seems to be about 1 MPG down. Didn't have the TS long enough to get good mileage reading.
I'm sure I'll try DP and Twildman eventually.
Hope that helps some.
