I do not know much about Edge products for the Hemi engine. I would check out this web site for your information. Some one on this forum could help you.

I am a diesel guy and have modified my engine and exhaust system . I am running a Smarty S67 with ME version software and a 5" Turbo Back Exhaust system. I also have three Isspro Exhaust, Boost and Trans temp gages mounted in the A-pillar.
I also know that I am my own warranty station.
You just need to decided if you want the warranty or not. In my case the local Dodge dealer was closed and the Dodge brand was given to a Chrysler dealer.
I new I was in trouble when I had to show their techs were to grease the front drive shaft and then was told there was no grease fitting there.
