Your Asian market cars have different ECMs than the US market ones.

The US market ones aggressively maintain stoich (14.7 AFR) to comply with our emissions standards. There are many devices that can be purchased for $50 to $500 that promise power and economy gains, but all that I have seen tested have failed to deliver.

$225 would be far better spent on a used AEM F/IC, which at least has the ability to modify the output of the AFR sensor to fool the ECM into thinking that it is running at stoich, while the actual AFR is adjusted.
