Hello, I was looking into getting a kit for my NA VG motor. From reading the other posts I have gathered that the improvements on power with lets say the Progressive kit was small, but there is an improvement in gas milage. Am I correct? If so, this intrigues me because of gas prices. What sort of gain should i expect if i get 18mpg now? If i am totally off, then please list some reasons a person with an NA motor would want to purchase this kit. I am very interested! Thanks! -Shimms |

Wow must have missed this post. N/A motors that are not high compression or do not require premium fuel would be better off doing flow mods such as cold air intakes and exhaust vs alcohol injection. The gains would be minmum. Now when you can go from 91 octain to 87 octane that's were you save the money.
