What are you wanting to know about it? I have a few friends running the entire setup and love it. I also here the make a cold weather kit since MN gets REEEAAAAAAAAAAAALLLLLLLLLLLLYYYYYYYYYYYY cold in the winter.
:rant I think 100K is a little long to go on coolant in these engines. Now I'm no mechanic but I think 50K would be a better interval to be safe. .00002:sorry
You can get away with a EGR delete as long as you don't get emissions testing. I would leave the EGR valve intact because that is a obvious thing that would thrown a red flag. If you want to be real sneaky look at this>BPD
I would recommend cleaning your EGR valve every 10K.
You can also tell if it has a EGR delete by looking for the EGR cooler or if the EGR valve gets dirty after you clean it the EGR system is working as to EPA regs. IE: no EGR delete.
