I am really interested in this tuner. But with an R/T 6-speed do they have a tuner for us yet? My son installed his on an SRT-8 Magnum and may I say it rocks. 93 octain tune and this beast is killer. You can't go more than 1/2 throttle on a damp street. Nothing but wheel spin. We will see when we go home today. Roads will be dry. If anyone knows if they have one for R/T 6-speeds... let me know.
