I am new to this thread, and i am sure this topic has been discussed before. I have the edge juice on my 2008 cummins. They told me as well as others that it would void my warranty. Anyways i have had the check engine light on for about 2 weeks. I took it in to the dealer yesterday to have it checked out. They told me that they could not send my computer results to Dodge to find the cause because the truck had been tampered with. They just told me they would reset the computer this time, but to take off that edge until the warranty has ran out. Any advice would be appreciated.
