Is this something that can be set in EFI live say like an always on Jake brake? I know that Banks and Fleece performance have made a turbo brake and boost controller but I was wanting to do something a little more simple (and cheaper) which would be to have the turbo vanes closed at 0% throttle or maybe 1-2% throttle. Anyone done this and how did it work out?
In my mind it would probably be best when a DSP switch comes out for the LBZ that way I can have two replica tunes, one with the "turbo brake" and one without that way I can turn it on and off whenever I need or don't need it.
