Does anyone have any experience using the Cutler's ACBC?

https://www.cpcracing.com/altitude-c...st-controller/

I was interested to hear anyone's thoughts. I also posted this in the Arctic Cat section since Cutler's is an Arctic Cat performance company, but I was considering using it on an Apex with a 2860RS turbo (same turbo used in CPC's turbo kits). The controller automatically adjusts boost for changes in atmospheric pressure (elevation). It replaces the waste gate actuator on the turbo. If it works as advertised, it would be great, but I am a bit leery about trying it out without hearing any feedback. I believe it simply uses exhaust manifold pressure to activate the waste gate. Once set (via preload on a spring) the waste gate should open once the exhaust manifold pressure reaches a preset value.

Any thoughts on this would be appreciated.
