Jet Mass air sensor

A friend of mine has a 13 Tacoma and bought one of the Jet Mass Air Sensors and he claims he gets 2-3 more MPG since install. I just don't see how this is possible so I'm reaching out to see if any of you have installed one. If you have, did you notice any difference? They're only like 150 and if I will get a mileage gain then it may just be worth it to me. Thanks!

 

@Torspd @Lucario Runner ....wut say u?

 

If it adjusts the reading of the g/s of air that the computer is seeing, there is a possibility. Does it? I do not know.

 

I've read quite a bit on it and there is nothing that says it's any different than OEM. Just Jet making claims of gains but it doesn't say how the gains are made

 

just like a throttle body spacer for 2nd gens.

 

If this is what you are talking about: http://jetchip.com/shop/performance-engine-upgrades/powr-flo-mass-air-sensor-31/ , then that looks like a bigger flow restriction than the stock one on my 14.
