EGR and AIR delete question
EGR and AIR delete question Hey guys, so i don't know if i should delete my EGR and AIR. I've read numerous threads on here about it and i can't decide. The egr just looks like crap. I want to take that off and the AIR. I also have pacesetter longtubes that have the EGR and AIR hook ups. Will that affect anything? And also what about tuning. My car already has a tune for full exhaust and a ported throttle body, so if i took the EGR and AIR off would the SES light come on and i'd have to get it re-tuned? I just need some advice on this. I've only had my ls1 for a couple months. Thanks in advance
You will have to get the AIR and EGR block off plates for the headers and intake. Also, you will probably get a CEL that needs tuned but, other than that you shouldn't have anything to worry about except for the light being on. If you have to pass emissions inspections I personally would just leave it alone.

Yea ima do a EGR/AIR delete but when I do my headers and tune in the same time. Im sure Indiana and Illinois are the same for emission testing, just plug and thats it, they don't do visual inspections so we'll be good

Where I am in Indiana there is no inspections. If they do just a plug and check you might want to ask someone if it checks to see if the EGR has been disabled. That is how it will be turned off in the tuning. As for the air, the air is there to help ignite the CATS when you start the car. If you are going to continue to run stock CATS you might as well leave it. If you are going to run high flow CATS go ahead and get rid of it. Just my 2 cents

I think I'm planning to do a ORY. I was gonna stay catted but I decided to stay with my SLP Dual/Dual catback so if I do headers w/ a catted y, it's going to sound stock pretty much still.

Its pretty easy to turn that stuff off. If you can you should go back to the original tuner because they have the credits that were used on your car in the first place. Unless you have a tuner that has the unlimited package for your model year car and he should do it pretty cheap. As for the block off plates, I forgot to mention you can just weld the holes closed or make plates....

The only thing im worried about is the tune. I bought my car already tuned for a ported throttle body, ported maf, pacesetter longtubes, slp catted y, and slp loudmouth. Will plugging it in to a programmer to delete the codes mess that tune up?

He will pull the tune, edit the EGR and AIR settings then flash it back in. Wont change anything in the tune unless he changes it. Are you sure it was tuned?
So i am not sure what to do. I really want to delete them both but im just worried about the tune. How much would it be for a perf. shop to delete them out of my current custom tune? i cant really afford my own tuner and i dont really wanna take it all off and have an ses light staring at me.

Do you know who the original tuner is?
