Still futzing with the throttle setup - I have this occasional hang where it won't settle to closed throttle value. K-Tuned said it absolutely cannot be caused by the TPS, they suggested cracking the butterfly 1/4 turn of base setting. So, I did that today & reset the TPS to match. See how that goes.

Playing with breather options - removed the PCV & added a much larger vent tube, since there is not vacuum draw in this case. Want to see if it helps with the oil smoke on deceleration I have been experiencing.
16mm ID EDPM tube

Used a Volvo EVAP hose for this end - without the formed elbow, the tube will kink somewhat
Used a #8 to #10 AC barb slice to step the PCV housing from 13mm ID to 16mm ID

Also added a bridge clamp between the two AC hoses to prevent vibration-related stress
