I am currently doing the Aristo swap in my IS and I have searched and can't find a definite answer on how you would regulate boost (ie boost controller) if you remove all the 3 actuators on the seq. setup? BOV maybe?

 

Not sure if its the same as the VVTi but heres what we use to do to the mkiv supras

That only works if you could use the stock(aristo) ecu. And I believe I have my own answer. You don't wire the actual wastegate open, just the actuators! Then use the wastegate as you normally would.

 

^Ditto, exactly what I said at your house. Lol
