EGR Delete Q's

[MJ365]

For those with egr deletes on their trucks, did anyone have the problem with the boost dropping off when the egr is disabled? I originally had the egr blocked when I got the truck but had to re-enable it when the flash came out that checked for egr operation so I didn't have the boost and power loss issue. Now that I rolled my truck back to the original strat I figured I could go back to the way I had it and block it off. Problem is, even with it rolled back it still throws the egr codes and loses power when it is blocked and the valve is dummied up bolted one of the intake elbow bolts. Maybe there is a trick to it I did before that I can't remember. Any help will be appreciated.
