What'd you do just seal off the hole in your upper and the hole in your header then just delete the function with a chip? Or is there an actual chip? I have mine deleted but havn't gotten my car tuned to remove the actual EGR function. Now I have a check engine light...
Exhaust Gas Recirculator. It takes exhaust Gas and heats the Air going into the combustion chamber to help prevent engine knock with low grade fuel and it also helps in a small way to redirect exhaust gases to reburn. Actually if you live in a area with good gas this is not a worry but if you live in places like California with crummy low grade fuel you might start using mid or Premium if you get rid of the EGR system. Also remember some places will fail you if the EGR is not there even though it would pass the emission test.
I am not sure My car is already pretty fast. I do notice the car throttle responce is a bit better. The thing is the EGR puts heat into he intake and engine and that is something it does not need unless you have crapppy gas where you live.
im not an expert but i put long tube headers on my v6 caped the passenger side headder with a 1.50 screw on cap from home depot , cut out a ceral box to the shape of the return that goes to the engine at the manifold with some gasket sealer on it. The headers gave me an improvement so i dont know if the egr delete is a true a power gain? no lights came on. i thought it just recirculates gases / fuel that wasnt burnt to help emissions. ....any way no lights came on and car seems to like it.
