instead of blocking of the tube and getting your hands dirty...not that I don't like getting my hands dirty, but can't I just goto HPTuners>Engine>Airflow>EGR Airflow and zero that table out?

 

stupid question or no one is sure...bump...not that anything in the tuning section needs to be bumped to soon.

 

You may be able to turn it off and leave it there, but Im not sure if that would eliminate all of the exhaust gas getting into the intake and I know it wouldnt get rid of that crap sitting right at the front of the engine that looks like total **** which is the reason most get rid of it in the first place.
The EGR doesnt hurt performance, it is actually supposed to be cooler air than is normally seen in there. The drawbacks are
1. Its totally ugly and shitty looking and takes up space
2. that crap will turn the back of your TB into a total grime deposit and cause sticking TB.
Get your hands dirty and take that crap off man. It took me some time since I had to wedge a screw driver in there to hold the bottom bolt so I could unscrew it from the header. Normally it would take about 10 min if that.

 

yup go for it i removed mine last night and it looks totally better. took 10 mins not even.

 

I know I was asking if I could do it without taking it off, however I would take the 350 dollar POS off, I was just wondering. I am sure if you commanded the unit not to work, it will not let exhaust gases pass, hence zero at idle. Where and what I was really interested in knowing is, obviously the PCM will shoot you EGR codes and just turning those off is an option of course, but what is being effected by the absence of the system? Besides the obvious, your TB plate will love you for it. Seems to me the timing tables, MAP, and other settings will reference the "assumed" data of the EGR flow. Shouldn't we delete the assumed values as well, not just turn off the codes. I know it's no big thing, but if you are working your *** off to tune a performance minded truck down to the last degree and +-LTFT, wouldn't you like to know the effect of no crappy *** exhaust gas in your intake?

I did find on LS1Tech(recent thread), that they argue that you may run lean from the removal...minimal difference, but lean nevertheless. They say there is a timing table for just EGR.(I haven't had a chance to look through HPT yet) Deleting the EGR manually and not with in the PCM you can have up to 7 degrees of advance in some areas of your MAP. Interesting theory...or fact.

 

oh....ya. Tiburon shot me a message showing how to zero out those timing tables based on the EGR. Is that what you were looking for? I can forward you the info he sent me. Ya the tables will add timing based on the assumption that the "cooler" EGR gase recircualtion is taking place so you do want to zero out those tables. I took mine off, turned off the codes and zero'd out the tables, but I really dont feel like there was any difference at all. Certainly not a loss of 7* of timing like I removed.

 

yeh, I didn't think you'd notice...all of the adjustments are below the .52 g/cyl area on the EGR Correction table. Is there any other table I should worry about?

email is besi@deweygibson.com if ya got soemthing else. THANX!!!

 

dewmanshu, I noticed that your sig states that you have an 02 PCM upgrade...if that's the case you shouldn't have to do anything as the 02's did not come with EGR. When I installed my 02 PCM I just removed my EGR valve and pipe and blocked off the hole in the intake and the header. I ordered the block off plate for an 02 intake straight from the dealer and got the manifold/header block off from Thunder Racing (they also have the intake block off I believe).

 

Reeeeeeeeeeeeeeeeaaaaaaaaaaaaaally? This is a true statement, never thought of it, but budhayes3 there is surely alot EGR option stuff in the pcm (via HPT)...activated at that. Hmmm, I wonder if Allen just "turned on" or copied and pasted egr stuff from an older pcm with egr and 6.0 into the 02 pcm? Man you got me thinking on that one...oh well, it's in the pcm for sure, I can post a pic. It doesn't really matter anyway I have already removed it, I am actually finally gettign around to putting on the heads I wanted all along and this is definitely something that I wanted to cover...err take off while I am in there, along with a few other things. I just want to make sure all my bases are covered...so freaking tired of hearing "oh you didn't change your egr correction table, that would explain #7 piston having a hole in it...along with running 12.7/1 at WOT"...Thanks dude.

 

I still have the block off plate that shipped with the heads, and I was just gonna put a freeze plug in the radix.
