performance chips. Do they really increase MPG?

I've seen these ads regarding performance chips. Herer's one that staes a MPG increase-
SLR Motorsports

I'm curious if they really do increase MPG and if so, how hard are they to install?

11 Hyundai Elantra GLS
16 Honda Pilot LX
And a 1907 Baldwin Steam Locomotive (Really)
