If you live in an area where you have to pass emissions DO NOT mess with your EGR. You will fail if you mess with it. As far as hp, gains would be minimal. EGR stands for exhaust gas recurculation. basically the way it works is by letting some exhuast gas back into the intake manifold. the exhaust gas is mixed in the combustion chamber and burned along with the new air. the reason they do this is for emissions and and to lower the combustion temperature. you could free up a lil power if you went non EGR, but you could be in some trouble come time for an emissions test.

you wont gain any power from messing with the EGR

[JKG97LTD]

how could you not gain any power. i know that with v8's going non EGR frees up some power. hell you are burning exhaust gas in your combustion chambers. 97 you might be right, it might not work for his engine, but for others it does work.

ur only burning exhuast gases when certian conditions r met by the manufactuer's specs. basicly when u need the hp the egr valve is not going to be open.

When my EGR valve got clogged,my car friggin BURNT thru gas and it sucked major ass..DON'T Mess with it!

I believe the EGR is only active at part throttle. At WOT it is of no concern therefore its not gonna make a difference when you get on it.
