After I installed my tune Monday I noticed on my EVIC that my MPG's dropped by 3 after installing the 87 octane tune. Has anyone else experienced this?
One other question. When I installed my Diablosport tune on my 2005 hemi grand Cherokee I had a choice of transmission tunes but was not the case with my 2012. Is it just one transmission reprogram now?g

Re: MPG's drop after tune on 2012 JGC
Mine has had a drop on the 91 tune. But that's b/c I am taking advantage of the additional performance (aka gunning it 
).
Have you tried the MPG tune. I think that one specifically is set to maximize efficiency of fuel consumption. I think the other ones inherently burn more fuel to gain the additional performance.

I was interested in the performance aspect but I've never had a tuned vehicle lose MPG's before.2011JGC wrote:Mine has had a drop on the 91 tune. But that's b/c I am taking advantage of the additional performance (aka gunning it
