I have the 65 HP in my CTS gryphon. I am thinking they would be the same as the tunes are from PHP.
I think it will be difficult to determine which would do best in your vehicle. They are both VERY similar and I could not get an answer from the guys at PHP. Pretty much summed it up to just get the 65HP tune.
The reason I say to not try to figure out which is better, as there are so many combinations of how our trucks are set up and modified, it will be very hard to figure out how one compares to another. Look at weight differences between an EX and a truck. A truck may be running your combo with one chip to compare an EX with almost the same mods and the other tune.
I would say get the 65 and roll with it. You are looking for ecomomy and still get modest power gain from your truck, correct?
