Just for giggles I decided to crank up the fuel pressure as much as it would go until it sputtered or missed but it didn`t so I stopped at 9 psi. and left it. Per Continental Converters instructions I took my car out and at 2000 rpm`s in 3rd gear I mashed the gas and it flashed to around 4000-4500 then blew the tires off. Is there another way to check a vert other than the rpm`s mph math deal? Thankxx..
