I've run Bill's programming via the Edge Evolution, then a TS, then DI, then DP and NOW I run Tony's.
Evo was generic, great power but smoked like a freight train in the 100hp. Good entry level programmer.
TS made a little more power than the Evo but rattled something fierce from excessive timing, that was 2004 though. Egt's came up quick and smoke was thick.
DI went "smokeless" programs and I bought a chip from David. I had issues with it. The programs were okay but not what I was looking for and can't drive to Houston for live tuning.
DP was used when I went to dual HPOPs. Idle was poor, smoke was on par with TS. EGTs were manageable. Again...couldn't drive to Asheville for live tuning.
Then I MET this guy named Tony. I liked his attitude toward tuning and bought a chip at the '07 NTXPsA rally. Idle is smooth, throttle response is what I want. EGTs are better than with DP. I can gross 21k lbs towing in tow program at 65mph with egt's at 700-850 on flat ground in 6th gear. I'm not going to fly by anyone but I can accelerate to 75mph effortlessly and still stay under 900 degrees. Total Diesel Performance will handle all my tuning now. All trucks are different and HP ratings on chips are BS in my opinion, I have "stockish", tow, daily driver and extreme.
