I am considering deleting the EGR on my car and have a tuned PCM made to go with it. My question is, does anyone have an EGR delete? It doesn't really matter which engine, I just want to know how much performance increase there is. If the difference isn't noticeable, I wont bother.

 

if u live in a state that does testing don't bother you will never pass, with these newer cars i have heard that it can decrease mpg

 

No power increase at all. EGR only recirculates exhaust gas at part throttle- never at idle (engines have a hard enough time keeping a steady smooth idle as it is) and never at WOT.

I turned off EGR (well I set the pcm disable temperature so high that it would never come on) on my GTP after seeing all the carbon buildup in the intake manifold. After taking like a 2-3 mpg hit (even after a little tweaking on my tune), I decided it wasn't worth it and re-enabled it. Not much way to get around it- at part throttle where you don't need all the power, it partially fills your cylinders with inert gas- meaning less fresh air coming in and less fuel needed also.

I do have it completely removed on my monte- thats partially for looks, partially for weight savings, but mostly for the fact that I don't want it plugging up my intercooler core (something most people don't have to worry about).

 

yeah man, whats said above^^^ it will waste gas and it closes all the way when you got the gas all the way down(WOT).

 

Thanks guys. If there is no performance increase, I'll just leave it on.

 

yeah, good idea. the only real problem with having an EGR is that it can get clogged or gunked up.
