I'm running an EJWA CTS most of the time. When I really want to get some power, I put my Comp on. For how well the EJWA and/or Comp suit me, there is no reason for me to stray to any other brand then Edge. From what I have hear, and in my experiences, Edge's customer service is second to none.
I have also hear more stories about how the Quad is picky compared to an Edge. Seems the Edge works on every truck, every time, where as the Quad likes certain trucks.

comp box ran both quad arrived bad 2 times I gave up.

Quad. Period. :tu::tu::tu::tu:

I have 2 adr boxes...one with the tourq monster tune and one with a fuel economy tune...I had one box burn up and the adr ppl worked with me great to make things right...other then that the adr is great in my opinion
