Can't imagine a high-perf making your smog-testing problems any easier.
And I was kidding! It's a well-known "fact" amongst the ill-informed that chips such as I suggest cause the oil to congeal in these engines.
The chips simply re-map certain parameters of engine operation. If you buy one, get it from a guy who has an in-house dyno and can demonstrate the improvement(s). Some of these things are a lot like the 200-mpg carburetor, except the eeeeevvvillll Big Oil guys who deliver refined gasoline to us for less than the cost of bottled water haven't (yet) bought up the rights to them all...
A huffer for the Highlander will run about the same as for that Camry you so carelessly wrecked and sent off to no good end.
I think you'll be happier leaving it stock, saving your money for an all-motor kit car of some sort.
