I bought an SCT2 from them this spring to replace/upgrade my Diablo tuner and the end results were great. I wasn't that impressed with the 93 tune (I usually use the 91 which is incredible) so I'm not sure if it's a difference in the tune, the tranny program or if the 94 e5 fuel I am using is to blame. I have been intending to contact Brenspeed and ask but it's not all that high of a priority.
Otherwise, service and the rest are all top notch.
