EGR stumble even after SCT tune?

I got the SCT flasher, and i flashed my PCM to 93 with various options, one of which is EGR disable, mostly because before i was having that egr stumble. It fixed it for a while. Then my clutch went out, after i installed my new clutch i decided to remove the EGR system components since its no longer necessary. Well i did, i removed the tube that goes from the header to the intake, pluged up the header, and plugged up the other side of the egr tube. Now it stumbles still. If i hold my hand over the intake, and allow more air in, itll stay on, if i dont itll just stall itself out. I have NO idea what could be up, new plugs etc. returned it to stock, then back to 93, then stock then 93 again, each time, didnt fix it. Any ideas?


Yes i have 93 in the tank.
