Mine has been blocked since about 1500 miles did not notice any difference in the spool up and as far as egts, I didn't have my gages on before I blocked the egr off. Sea04dmax, are putting the finger stick in also? The main reason I did it is to keep all the soot out of my motor. I put the finger stick on to get rid of my cat and straight pipe my exhaust.

With the LLY's its a hit and miss whether you need the Finger Stick or not. Just have try it and see because there have been federal and CA trucks that have set codes. Mine is a federal emissions truck and it set the code. If you straight pipe and/or remove the cat your pretty much guaranteed to need the Stick. Contrary to popular belief it wont improve spooling, mileage, egt's, or temps. It DOES keep your engine and oil clean. I took my intake apart at 5K and was shocked at what I saw. I have also by-passed the PCV system because its even worse. I blew an intercooler boot and saw oil dripping out. The PCV system pumps oil into the turbo intake and sends it right through the intercooler. Not good for the turbo or the intercooler.

You are one of the few lucky ones. Most are going to have major problems trying to get the nuts broke loose. I almost started to put heat on mine.

I would wager that you do have codes, just not lighting the CEL. Either way, I doubt that it hurts performance.
