So this tuner has 4 settings:
1. Economy +30hp +60tq
2. Towing +60hp +135tq
3. Performance +85hp +185tq
4. Extreme +100hp +220tq.
Stock is 360hp and 650tq. There's "race" versions of this tuner that will do +225hp and +335tq with just a tuner. It's really amazing.
The transmission builders agree that +85-100hp is the most you can go without doing damage to the transmission.
What's interesting is that I'm getting slightly better numbers on level 3 than I am on level 1. Ever so slightly, like 0.5mpg, and completely unscientific, just watching the mpg on the dash readout. Many users find the same thing, but I find it weird that the designers of the product wouldn't make the Economy setting the most economical?
1. maybe level 3 is more efficient, but it's harder to stay out of the high power.
2. maybe it's a function of using more power smarter via pulse/glide theory.
