I would like to delete my EGR off my LQ4 because 1: its UGLY & 2: I want to get the Schoenfeld Headers and there is no EGR port in them. My buddy has an 02 Silverado and doing a tune up on it this past weekend I noticed that his never came with an EGR.
So im looking for the pros and cons of keeping it and deleting it. I dont have visual inspection for emissions here in Ohio and I know I can get it deleted out of the computer.
Little bit of weight loss? :lol: I don't really see any cons if it is done correctly and you don't have emissions to worry about.
Well I have emissions but no VISUAL inspection like some states have. I have been told that knock could be more pronounced. Cylinder temps would be higher. But with the right cam choice the temps would be ok.
This truck is a DD and occasional track toy.
I believe you wouldn't pass emissions cause your HC would be too high, maybe NOX also.
Mine passes just fine without EGR.
You removed yours? Or never came with one.
Removed it when I installed long tubes.
it will pass, they wont do a 'sniffer' test. just visual and scan for codes.Quote:

Just remove it and tune it out, I passed my emissions with LT's, tinted windows, a turbo, a cam, and a big nitrous plate on the front of my truck, and it passed with flying colors. The only thing the DMV guy said was that the truck sounds funny :lol: I simply smiled and turned the knob up and then proceeded to do a massive rolling smokey as I left the station :).....And the only time that timing normally gets pulled is when the SES comes on for the motor ( ie: evap, knock, misfire..etc ) You should be fine as long as you have a good tuner that knows what he is doing
How did yall go about removing the physical pump? shorter belt or dummy pulley? I have a 99 sierra and getting ready to add LT's.
im guessing your talking about the egr valve? there are block off plates for bothQuote:

Just remove the Smog Pump and get a new belt for a setup that does not have smog installed (00+ trucks).Quote:

Would anyone have some info on what emissions equipment are on the 99-02's? I live in southern California and am looking for a regular cab short bed in that year range. I am in love with the idea of during an LS3 swap. Thanks in advance everyone.
