Sorry, I dyno'd my car last year befor I put in AEM Fuel rails, and I dyno'd it this year and since the install I noticed beter mileage on the highway and more peace of mind knowing that a high volume fuel rail not only provides your engine with additional fuel needed for more horsepower, it also helps stifle disruptive fuel injector pulsations. By dampening the pulsations created by the fuel injectors you’re guaranteed more regular fuel delivery under all conditions. Also the quote "Fuel rails are rice", makes no sence, you see fuel rails on everything high performance, from 350 vette motors to 4 banger hondas....
