    how do i disable the egr

    how do i disable the egr valve and componets. i am under the assumption that this will create better fuel economy and maybe like 5 more hp. not for sure though. ive got a pretty decent idea to stop the flow to the intake. but electronics lose me.

    Gas Mileage Question?

    Will vacuum leaks decrease your gas mileage? I understand that the pcv valve has a horrible reputation about leaking. so i am just going to start buying and replacing all the sensors (MAF, IAC) and such. and of course the pcv. just wondering if these things affect fuel mileage.
