That is insane.
There are many on this very site claiming such improvements and more.
Anyone that has done ANY research KNOWS the 14.7 A/F ratios are NOT the best for the car or MPG it is correct for the Cat, it insures left over gas to keep the cat hot and running.
The 1980's Camaro TPI system could do it outside the USA with the hidden Lean Burn Cruse setting turned on, in the USA they got 20/25 MPG outside the USA same car could do 30/35 MPG.
When turned on within the USA the car could also do 30/35 MPG.
