The MAF is held on with two screws. Simply loosen these and the MAF comes straight off. Personally, have you tried cleaning your MAF firstly? Some hints are provided here: Cleaning MAF Sensor. You do realise that the supercharger itself comes with the actuator attached as part of how it's purchased. Therefore, they don't simply just carry the supercharger only or the actuator only, neither are they going to pull one off a complete supercharger assembly. If you want either bit separately, you need to wait as it is a special order. It's not entirely based on who gets more money because think about it. If I was someone from Toyota, I would rather you get a new actuator than a completely new supercharger had it have failed during the warranty period. If you have the time, why don't you ring Eaton/Harrop and ask if you can get a replacement actuator for the R1320/HVT1320 that was designated for the TRD Aurion? You may have more luck going down that path. Ive just found out looking around the air filter box, and super charger the small hose inlet looking from front end of car towards it,theres a split where hose sits...I wonder if thats what makes VSC an d engine light go on?
