i got my tuner quite a while ago and i was told by the owner of 5 star i was one of the first brave souls to get the tune for the 3.7.

i have my reviews on his tune but they are mainly on the towing behave of it rather than just everyday driving. it drives great with it though. i have the 87 eco, 87 perf/tow, and 91 perf/tow.

I know this is a really old thread but wanted to see if anyone has updates on their 3.7 tune. After a year or two of using, do you still like it?

I have a 2014 3.7 that I'm considered having a 5 star added to, but am mainly looking for a power increase in that 0-40mph range. Does the 5 star work well for off the line power?

Or fill with E85 and put it in tow/haul and enjoy on an extremely hot day.
