Everyone has their favorite tuner. "Custom" does not = better or worse. A reputable tuning company, like Hypertech, puts lots of R&D into their tunes, some not so much.
I have had no trouble with mine, and I think you'd be very happy if you tuned yours, no matter if you chose a "custom" tuner (like DP) or an "off the shelf" tuner like Hypertech.
The key is to do your own research and decide for yourself.
The only thing wrong with your comments is. generic tunes are not good. Every truck will react differently. Plus the canned tunes do very littly for trans stratagies. Can you change shift points with their program? NO. Can you change TC lockup points? NO
A custom tuned chip is tuned for your particular vehicle. It can be tweaked to your liking. Sensitivity of the go pedal, shift points, shift harshness, TC control, etc. With a programmer what you get is all you get. Can't change it. Plus you have to stop & spend several min to change. Chip can shift on the fly.
One more time and I'm done with this. My 20hp tow tune produces MORE power than the 100 hp setting in the Hypertech. I'm not disputing their R&D program but when your tunes are for your individual truck & your individual driving needs & wants there's no argueing which it better let alone the trans controls. I have driven & towed with my truck using both so I have real world exp with both systems
here's a good example My truch is an early 99. The hypertech was for 99-00. My truck has smaller inj & turbo. You think they both will react the same to the programmer??
