Re: Predator u7137 help
My jeep seemed to run much better on the 91 performance tune. Loaded the 93 and it didn't feel as quick off the line and snappy in the mid ranges. I've just been running it in the mpg tune for a few weeks to maximize economy, and it definitely doesn't run as well as the 91 or 93... But 20-22mpg flat highway at 65 mph is worth it.
