1. The order form says that the 25hp Tow is for towing extremely heavy, and the 40hp Tow is for heavy towing. If I never tow over 6,000 lbs, why would I need these tunes? Is this order form written more for guys with the monster injectors, big HPOP, and a big turbo? I use a 25-30 HP towing tune all the time, even while towing less than 6-8K lbs. It's just to ensure that my wife or I don't HAVE to "drive by the pyrometer". Besides, we drive in an area in which we frequently have high headwinds (40-50 MPH) while driving. It's nice to be able to maintain 2000 RPM while towing and never exceed 1100 degrees. The moral of the story.......I don't base HP on weight only. A 4K lb. camper gets really heavy while driving into a 40 MPH headwind.

2. What difference would I see between the 25hp Tow and 40hp Tow?In a nutshell, more power in the 40 HP program due to less of a worry about EGTs and the transmission.

3. What would be the difference between the 65hp Performance tune and the 65hp Daily Driver? Would one use more fuel than the other?Bill will have to answer that one because I don't have them to compare.

4. What would happen if I tried the 100hp Performance tune? You would LOVE driving your truck. Every other tune would become mundane and boring while commuting to work.

5. I don't want much smoke, will the 65hp Performance tune cause a lot of smoke? I wouldn't think so. Besides, with the tunes of Bill's that I have tried, it takes slightly more pedal to hit the "aggressive" point in the fuel curves. If you TRY to smoke, you will smoke (not a whole lot with a 65 HP program anyway) because it takes more accelerator pedal input to get smoke. With other brands of tuning I have used, it can be hard to not smoke even while taking off normally.

6. I currently roll the truck down to the end of the driveway in neutral before I start it so I don't wake the kids. How much quieter is the Whisper Mode?Bill, please correct me if I'm wrong. I don't have any Whisper Mode tunes. However, I believe that the Whisper mode only works when the engine is warm. I am not sure about this though so Bill will have to give you a definite answer.

Thanks,
Shawn
I answered what I could.
