has anyone played with tuning?

Hold off for now....  supposedly, the egr is deleted. I think it would be better with one, but the deletes vs egrs can't agree one way or the other.  I can always add it in, right?  Ok. Bring them. What's the damage?

Is this 1MohrFiero's package?  If so, I just see that there's no EGR included, even though the pigtail is there.  That indicates it's wired for it.  The EGR can be tuned in or out on the ECM.  Even if the EGR is there and plugged in, it can be turned off with programming.

It's the one from Riddick85. It's set up for a 4speed dizzy and he claims no egr, but it would be easier to pin one in before i install the harness. I suspect I'll have to get the tune modified, so they can enable egr when that takes place. Unless it's better without it. What do you think?

...That wouldn't be fair to my wife, who has put up with my endless tinkering and cussing in the garage for months now.

When the wrenches and the "words" start flying, my wife reminds me, "Remember... This is what you do for fun!"

She's like that.

Kick you when your down, right? Lol

Some have removed the EGR and blocked it off I think mostly to eliminate the problems associated with the vacuum style EGR.  There's no gain of hp or mpg by disabling since the valve and solenoid don't work full time.  Pontiac went to a lot of time and expense with the system, so there's a good reason for it being there.  Some have reported burned pistons after removing or disabling it. 

The Digital EGR could be mounted and wired in, but turned off in the ECM and turned back on when you wanted.  I'd suggest having it installed, whether you use it or not.
