I went thru the forums and checked it out, and was able to figure out that, the groove creates a small vac leak. the engine gets unmetered air and the engine leans way out for better MPG. DAMAGING effects... Add to that, the bogus claims. look at the '93 GMC or the '94. 1 claims 125% increse ( 38 MPG total roughly ) and the other 65%. both bogus, especially being they are TBI injected and his mod puts an outside oxygen source directly into the mixture..
a few things, if that was true. it never idle, it because it'sefi,would add fuel,as the o2 sensor reads lean..
