I updated my tuner and have only tried the 87 tune. I will try the others as I go. My question is the crawl tune only for off road. So for those of you that use the crawl tune do just tune once you get onsite. Also is it worth it and what does the crawl tune change.

 

I'm interested in this too.

I went wheeling this weekend for 2 days and totally forgot to try it out.
