Why tune out air/egr
Just curious im gonna get a tune from LSX and was wondering all i have is a hooker muffler, exhuast cut out, slp lid, tb bypass, 160 thermo, 4.10's, my question is why delete air and egr is it worth deleting them even if i have the stock headers with the stock ypipe in other words what are the benefits of deleting them. I am gonna get a tune regardless just trying to figure out should i just go ahead and delete air and egr as well.

Weight delete, a tiny bit of power from no EGR, and a lot better looking with out.
01 dont have egr tho... correct?

2001 shouldn't have egr, only 98-00 years. Removing the air system will clean up your engine bay and make things much eaiser to get to. The air will have to be tuned out so you don't get a SES light. That air crap isn't good unless you live in a place where it gets real cold like Alaska. I live in Colorado and have no issues without the air system.2010 Camaro

do you plan on doing headers without cats at some point? If not then just leave the a.i.r. system alone but if you think you'll be doing headers without cats at some point then go a head and have it removed. I won't hurt to have it removed anyhow even if you keep everything.

well i might just remove cats and thats about it, doing headers is not gonna be for a long time. Ill just have him tune out the Air and 02's and the rest ill leave up to him for tuning the car to get the most power out of it, i have to get a tune anyway mainly because im going with 4.10's need my speedo adjusted, cags delete will be nice and picking up a few ponies wont hurt either. Ill get the tune from LSX next week or the week after and monday i should be installing my gears.

Can EVAP be tuned out/ turned off? The system was messed with before I bought my car and I just dont care to replace everything missing.

The solenoid is missing along with some of the hoses under the hood. Thats all that I can see but there may be more. I mostly just want my SES light out.

The truth is that EVAP saves you a lot of money by recapturing fuel vapors that would otherwise be released though a vented gas cap. I forget the exact number, but a properly functioning EVAP system will save you hundreds of dollars in fuel cost over the life of the vehicle vs. a vented system like the old cars had.
EVAP prevents hydrocarbons vapors from entering the air and it keeps the gas in your tank where it belongs...win win situation for the environment and for your wallet.
