you mean that if you flash back to stock now with supercharger, it enables but with custom tune not?
did you try to drive for many miles with vvt off and then stop while idling to see if vvt goes to 1?
after rebuild my engine too is slow tl activate vvt, but after a while it stays on
tune should have jothing to do with this
just go drive it with vvt off keep it off boost and will go on eventually
if it s like mine, it can be slow each time you flash, specially if warm
try to flash while totally cold engine
Ecu wants to see at least 2 complete cycle (comprehensive of 2 cranking and starting of engine) with vvt on before activate it immediately at each start normally
