They picture a chip, but the description says "The GF module installs
into your VOLKSWAGEN VANAGON's engine bay and is connected via 2 wires
that plug into the IAT sensor."

My bet is, it's a $0.03 resistor with $0.25 worth of wire/connectors,
which slightly changes the A/F ratio. The "60 HP" is BS. The $400 on
sale for $70, more so. GFchips no doubt stands for Get F*. (Fleeced,
not what the mods were thinking that meant :-) )

As Barnum said, TASBEM. Might as well spend your money on an HHO
generator.
