what are you guys using for programmers and tunes? was looking at hemi fever tunes for my 5.7 but would like to hear what others are using.
There is an element to this question that is perhaps equivalent to asking on the race board about power-glide vs 727, or dana vs 9 inch, or even "what is the proper pinion angle"....
Two options that seem big on FB - Greene Racing and Flyin' Ryan Performance. I spoke to hemi fever a few times - seemed like a nice guy. Another possible option OST Dyno - used to post here on Moparts. No personal experience with any of these as far as tunes. A few years ago I tried to procharge my ram 2500 hemi. The programming was kind of a nightmare and I gave up. Good luck.
