The best I could do with my RX330 was filling up with Premium 91. 
.....
although seriously, it was an upgrade compared to the most likely least expensive low grade fuel the previous owner left in the gas tank.

if they were not, some would be tempted to throw in a Chevy 427-cubic-inch V-8 motor.

So I take it No one here has actually done or heard of any modifications on this car as yet Seems I might be the only one ha ha The usual chip and pipe is said to give more power but now very slight and at the cost of your noise level.
Think ill look the IS350 ECU and see if its adaptable

If you want more power, first thing to do would be install an electronic throttle controller like the Apexi Smart Accel Controller. In the quest for the best mpg's, these cars are slow to respond. With and ECT controller, all available power will be instant. Basically like installing a "sport" setting for your RX.

The pressure regulator setting on the NOX tank. This is not the intake manifold pressure. The pressure setting controls how much gas will go to the engine. A 30 lb setting is generally the highest you want to use on an engine that has not been beefed up.

All Toyota ECUs are encrypted: there is no "chip" that gives "more" power...don't waste your money...
Swapping the IS ECU is like opening a can of worms....expect your dash light up like a Christmas tree....
