How crucial are the lambda (oxygen) sensor and air temp sensor to the performance of a 1UZ? When using OEM wiring and EMU it is probably not even possible to run the engine without those, but with an aftermarket EMU there's a choice. My belief is that the engine was designed to work with those and that leaving them off would not give the best performance.
Secondly I would like to know where the 1UZ’s lambda sensor is normally situated; is it on one of the exhaust manifolds, or after the two pipes meet – the collector, if I remember correctly? In other words is it important that the gas from both banks is measured?
