Why?


Taking the egr off will kill the economy. EGR does not hurt performance at all. When you floor it the EGR closes giving full power. It only opens at steady cruise. It delutes the air charge and then the O2 sees it as a rich condition and leans out the fuel. Taking it off could cost you as much as 20% fuel economy.



Great build thread. Really nice work.

Thank you for the compliments! As for deleting the EGR, it is more for aesthetic purposes. I think that a cluttered engine bay is unsightly. I am routing all of my wires to that it hides as much as possible. And as far as fuel economy, if it really hurts me as much as you are saying I may hook it back up. There are so many people out there that have had the EGR deleted and tuned appropriately that are still getting mid 20's in mpg. I am not too concerned at this point, but might take it into consideration if it becomes a problem. I have HP tuners and can turn it on or off without costing anything but time. I didn't ruin anything when I deleted the system, so if I want it is just a matter of installing the components again and re-pinning the ecu.
