I had a Superchips Cortex ,
only ran it for about a month and couldn't sell it fast enough!
I've found a winning combo for a great launch, solid shifts and very little to no noticeable factory torque management....
Edge Torque Converter + Diablo Tune + Sonnax
MGH tells me there's a work around to use a TransGo shift kit on a 4G 545RFE now too.
That will be my next mod (it's only $69) !
BTW, the Sonnax is not
required if you want to get a custom Diablo tune done
....you're CMR can program the same line pressures for you and save you the $50
