Modding EGR valve for performance?
I've read before somewhere that the EGR can be bypassed to give the car more power.
I was also told the same by a tech at a shop this is possible by removing the rubber hose on the EGR and sealing the end of the hose off.
Decreased gas mileage isnt' a concern if I can get some power by bypassing (or whatever) the EGR.
Anyone have any input?
EDIT- OK. So I've been doing my research after I posted about my topic (booo on me.) Seeems there's not too much you can do. I've heard you can get a little extra push out of your car, but blocking the EGR adds the most power on 2jz-gte engines.

Upside: a couple of horses.
Downside: a permanent check engine light, (code 71, egr malfunction).
Easiest thing to do is disconnect the vacuum line going to the egr and see if it makes a difference. When the check engine light comes one, clear it by removing the "engine" fuse.

I'm guessing it hasn't been dynoed or anything, but how much of a difference will it make? 5HP?
I think I unplugged and capped the right hose, maybe not. Car doesn't seem to be any faster. I'll take a picture.
If I don't see any gains, is the EGR bad?

DevilDog,
Does the same thing work for resetting the GS check engine light? Which fuse? Any downside to doing it?
Thanks in advance - sorry for the hijack.
