Re: egr question
You can take it off, and yes, it will throw a code. The check engine light will come on, usually while cruising on the interstate or at a constant speed. I've heard that while the light is on, power is cut a little somehow, but it clears when you shut the truck off. In order to get rid of this, you'd need someone like Nolan (10secTy) to custom burn you a custom chip that would delete out the EGR trouble codes. Mine is off, and it only screws up every week or so. No big deal at all.

Re: egr question
Correct, from the Ultimate chip homepage:
"Special Features in the 3 bar Ultimate chip:
* Intercooler pump turn on earlier, occurring when the engine coolant
reaches 60 degrees F, thus eliminating the need for hard wiring the
pump to run continuously.
* Rev limiter raised to 5400 rpm.
* Over boost fuel cut retained for safety reasons (2-3psi above boost
level for that program)
* EGR disabled in all settings but the T1-15 and valet, so as to not heat
up intake.
* Knock retard is more aggressive (when knock is detected, timing will
be pulled out faster than stock)
* Max knock retard raised (the stock amount of retard is limited to 12.66
degrees, we raise this max to 18 degrees)
* Wide Band 02 sensor compatibility
* Faster turbo spool-up due to timing and fueling changes.
* First time boost disable eliminated, allowing full boost after start-up.
The factory and many aftermarket calibrations limit boost the first time
it is seen by the engine, creating difficulties at the track.
* The Ultimate chip comes with a display/switch unit, the size of a small
radar detector, or enclosed in a 2- 1/16” gauge enclosure to select
and view the current program. The gauge version fits in all 2 1/16”
gauge pods and comes with an 8+’ cable to easily reach the “A” pillar.
See pictures below.
* Knock indicator light.
* 3 different timing curves, from mild to aggressive.
* Several boost levels, from stock to 24psi."
I removed the EGR on my truck long ago, no codes for me either
