If I may add my .02, oem tunes as a whole are conservative. The Honda/Acura guys get NA tunes all the time that make DRAMATIC increases. The OEM tune being garbage means there is room for improvement. I would also argue that independent opinions ARE data. If multiple people are saying it feels better, faster, stronger, then it's probably true. You don't need a dyno to compete in the Pepsi challenge.1.) These results on a NA OEM motor from a tune alone is not feasible.
2.)The oem tune on a manual transmission JL is garbage. You can search the forum for many people who are in agreement.
3.) I’m still waiting for someone to post independent results from this tune. Not opinions on how it feels. I want to see data!
