Our tuner will be Darren at R&D dyno so far he is the one to have been the most pacient with use and keeps things on the low. We hear he is good with AEM and others so we are still waiting on more feed back. However we would like to deal with a company with good customer service and technical support. Thanks guys for anyother info.

 

use what the tuner knows... that way you wont ever have to deal with the maker of the system for support.
