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.

DevilDog, which fuse is that on the 90-94 LS400?

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?

Simply remove the fuse cover in the engine compartment. Large cover by the battery.The under side of the cover shows what fuse is where.

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.

If I was resetting your car I would simply unplug all the connectors at the ecu.

It's not worth the effort....nobody's going to feel 5 extra HP on a 4000lb Lexus

hmmm I removed the Main Engine fuse and nothing changed
