3 pulls to fully tune? Sorry, way off.
You can get WOT pretty close in 3 pulls if your base-line isn’t too far off. But a TRex is pretty damn radical and it’s probably going to take a LOT more than 3 pulls to get WOT dead-nuts. Part throttle, idle, cold start, quick throttle close etc. will need a lot more time than 3 pulls though.
I do agree though, I highly doubt it’s a PCV issue. LSXs are known for sucking a TON of oil through the PCV but that’s only on high rpm-deccel. That much smoke at idle and light throttle blips under no-load is not PCV related IMHO.
