I'm sure most would buy it again that have it. I have one and plan on buying another for Laura's car unless I see some unpassable deal on something else. The AVC-r and AFC can really work some magic together dyno tuning in the hands of someone with sense about them. Mine hits within .01 boost all day at the track. Some days with different temp and weather it might hit .03-.04 less than the last time I was at the track when I'm trying for really high boost. It will still hit within .01 all day of where it starts out at. That has nothing to do with the controller. Some days you just can't hit as high of boost with stock turbos with weather changes and if you're pushing them high. Mine was bouncing around all over the place at 1st when I had it wired to the injector pulse and had a couple boost leaks. I re-wired it for RPM's instead of injectors and fixed the boost leaks, now it's fine. LaterZ
