I just got finished putting a chip and stage 1 injectors in my OBS. I had the Superchips Microtuner on it before. After the change to a chip and stage 1's I would ESTIMATE my power gain (compared to my Superchips) at around 50 hp on the lowest setting which is supposedly "stock." On the extreme setting I am guessing 160+ I am really guessing on the extreme as I have been limiting myself on that setting due to a stock tranny
After stating that I hooked on to my trailer to see what the temps would do and with a 7500 lb CC Dually truck and a 9000 lb trailer I could pull any hill I wanted in ANY setting on the chip. Both of my tow positions make lower egt, while crusing or pulling a hill, than the stock setting although the egt does start to get hot if you are really hammering on it. The extreme would probably not be too good for towing due to the quick pedal and possible fuel consumption, but my Perf. Tow setting isn't down on power much at all from it.
I could get the egt's into dangerous levels if I put my foot to the floor for an extended period of time but I can pull a hill with the trailer starting at 65 at the bottom and be going 75+ at the top with egt no higher than 1350* on a monster hill.
And also towing with the cruise on is no problem. Not that I am a big fan of that, I just wanted to try it.
You would probably run out of fuel with stock injectors at some point so you may not have as much of an egt problem at full throttle. But believe my if you have your right foot on the floor that means you are pretty much screwin around, definitly not going to be typical for me to get over 1/2 throttle.
After reading this long drawn-out post you can see who I went with but I am not saying that DP is bad. There are countless members on here that are extremely happy with their product. What ever you end up with I am sure you will be happy with
