You can do an EGR bypass, but im not sure how to without deleting the code in the ECM first. (There isnt a pump, its an EGRV, Exhaust Gas Recirculation Valve) I did a writeup on what it does on another thread.

You will see a slight to noticeable decrease in fuel economy if you do this mod, normally.

You will probably keep getting codes lighting up. And like specialk said, I think that it would actually reduce the fuel economy.

what about running an after market intake would i be able do delete the code?or does the after market intake come with a spot for the EGR

that's why you get the code deleted, get yourself a handheld programmer... If your gonna start changing things like intake, exhaust, fuel, etc., you'll want one instead of bringing it to a shop every time you change something. just a thought.

Depends on your mods. A dynotune really only helps with major mods.

Kinda OT and very noobish- but isn't the really big one to have dynotuned after installation a cam?
