What of the Vaccum lines can I delete? Also can I remove the EGR solenoids and Bracket from the back of the intake without problems?

Not all of them, just the useless ones. So if I can delete the EGR that should eliminate most of them?
Provided you're planning to have your ECU appropriately "tuned" you can eliminate the EGR and SMOG systems and also eliminate the resulting DTC.
The vacuum line associated with the MAP sensor needs to stay in place and operational.
With the EGR system left in place and operational you can eliminate the SMOG system and the associated with vacuum lines without triggering a DTC, but this takes a little careful removal and sensor nipple capping.
Is it a requirement to tune the ECU if you do the deletes?
nipple capping.
I'm starting to sound like Steve83 now!
Ok cool thanks. So does this not work?

So going off of this information. I can remove the smog pump and associated vacume lines and just leave the tab/tad solenoids plugged in electrically?
My situation is this, my recently purchased truck is pretty much stock from what i have been able to gather from previous owners.
I know a 70mm throttle body and PO has said mild cam. Also straight pipes from cat. Convertors back. Thats all i know. So i have been gathering a few aftermarket parts and reading on this site. I am going to pull the engine to address an oil pan/ timing cover coolant leak. So while I’m there i am gonna install the the parts I’ve acquired. From LMR i have bassani shorty headers and off-road midpipe, the smog delete pulley with bore plugs, flex-a-lite 420 e-fan and stuckby harness. Tps and Os sensor. Just wanting to clean up the engine bay while in there. My thermactor
Solenoids are just hanging loose behind the tb, so i need to figure that out.im assuming after changing the tb there was no place to secure them so whoever just left them laying. Anyone ever have this issue after upgrade? Gonna do compression and leak down test before removal to check internal condition. Only 110k on engine and running good so i don’t foresee much there. So after all this i can update my signature and be able to communicate better.. sorry for the long post but help with the smog issue would be great.

Rick,
I got your PM ... apologies for not responding sooner.
I did some digging into old posts and I think post #4 in the thread linked below might assist you.
Let me me know if it doesn’t.
