I write this to anyone that curently or about to instal the EGR delete kit ... On some EGR delete kit on the back blocking plate that bolt on the exhaust manifold is having the hole is screw in with a copper arlen bolt , make sure you got it tight enough or you can find some thing els to use instead of that copper screw or it will pushed out due to exhaust brake at high pressure ... It just happened to me about an hour ago and it did freak the heck out of me ... The release of high air presure when the exhaust brake is on sound like a blow turbo
