New to the forum I've had my titan for about 8 months now it's a 2012 crew cab 4x4 flex fuel 2.94 gears all stock except Flowmaster 10 series muffler swap and cooper stt 275 70 18. I just got my hypertech max energy and right now I have it set on the 87 tune but I was wondering if there is a performance difference between the 87 vs 93 tune if there is I'll use the 93 but I had read that the bdgt 87 and 93 were very close so that's why I ask anyways thanks for any info.
