HVAC is about right for the price, that's just the turbo alone. it will not bolt to a Exh. manifold without an adapter, all the plumbing needs to be reconfigured. A air compressor, tank, lines and a control valve are needed to control the actuator.
Nowel, as for the controller, it needs some fine tunning and possibly different modes for driving, towing and racing.
Boost is right off the line with my mildly fueled truck. With the comp on level 1x4 I can hit 40#s boost. Max boost I've taken it to is 46# @ 160K turbo speed.
I'm taking it easy on the turbo, to find out what it's limits are without blowing it up, even though
abledog did bark it pretty good last night @ 40#s of boost. :--)
EGTs are down a couple hundred degrees.
TDK, you couldn't't open my hood with the jaws of life. All of this is proprietary.
