I bought the ULTIMATE PERFORMANCE CHIP for my 04 LEXUS RX 330. This chip is supposed to be connected to the two wires going to the IAT sensor. Unfortunately, the sensor is part of the MAF (Mass Air flow Sensor) assembly and the plug has 5 wires. I have no idea which two wires go to the IAT (Intake Air Temperature Sensor). Could someone help me on this? Thanks, Paul

I have always believed these 'chips' don't do much - the manufacturer has optimized the engine and its management to the best of its ability, and there is little chance that an outside (smaller) co. could do better. But I am always curious.... could you let us know if the chip does improve power / torque / mileage? [Good luck!]
