Has anyone heard of the gadgetman.com?
he claims to increase fuel efficiency (mpg) by adding a specific groove in the throttle body near the butterfly valve on certain vehicles?
I know this is the HOLY GRAIL and one of the oldest scams since the internal combustion engine was designed, but He supports his claims with a lot of data from a lot of people that have modified or had their vehicles modified.
Has anybody ever tried it on the SANTA FE or any vehicle ?
