Doubt they'll give you anything close to 20hp. maybe a few hp if your fuel too lean.

I know with older model toyota 86-91 you can open up the mass air flow sensor and adjust spring to trick ECU that more air is comming in. Same thing with that M-module chip. To make it run richer.

Why Toyota people do this is because when you go intake/ free exhaust is that your mixture might be a little lean. So you do the mod for more fuel.

However newer cars are better at fuel ratio. If your fuel mixture is ok, you'll be adding more fuel than needed, and ruin the o2 sensor, cat, and deposits, higher emisions.

I find it interesting that it claims to make your fuel mix richer, yet doesn't reduce the fuel economy. /sniff sniff, anyone else smell bullshit?
