Default HP TUner EGR Question

I finally created my first tune for Marie and I tried throwing in the Disable EGR.

It immediately triggered an SES light.

1. Can it be Disabled in HP Tuners without triggering SES light?

2. Can it be Disabled and still pass OBDII Emmisions?

I don't think I have to pass emmisions in NC but I still would like to set it that way just incase.

I'm sitll running on CT plates and License for now so I'm good for awhile.

yes, any of the tuning packages will allow you to turn off EGR

OK SO how do I do both?
How do I delete the codes?
How do I have it still pass OBDII?

Because when I just disabled it an SES Light came on and it just ran like ****.

I know when I do that it triggers an SES light.

I wanna disable it that way and still not trigger SES light.

I don't know how to access and change hte codes so this doesn't happen.

so the number 3 tells the VCM to not report an error? Excellent. So will that trigger it in obdII still?

Question. IF I'm running way rich during normal driveing and mid rpms at WOT but hitting max duty cycle at high rpms and leaning out. Will Disabling my EGR lean me out more?

Dude I'm not messin with my tune at all untill after weds.

Tonight I'm installin the new AC DELCO MAF
Tuesday I'm having the LT's installed with my Xpipe.
Weds. I'm going back in to the shop to have them Dyno it.

I plan on putting 50 to 100 miles on it tuesday night after resetting the ltrims to relearn. So on weds I'll get accurate info and have wideband af settings to tune with.

Then I just put all my schedule and planning on hold untill I get the Wideband and HP tuner upgrades to properly use the software.

YOu guys are right. I shoudln't be doing any modding until I know what I'm doing with this software. Except for injectors though. Because I'm at 97% Duty cycle at 5k rpms
