I bought a new intake manifold from Brenmart Performance in Ohio and need to block off the egr and was wondering if it could be detuned from the pcu so I can still pass an "E" test. In Jan. this year the Minestry Of the Enviroment which dictates "E" tests changed the test, they now plug into the OBD port to find codes which could fail the car. Any help with this would be appreciated. The manifold is somewhat similar to the 6.1, it is good for 35hp and 30ft.lb. of torque.

 

I disconnected/removed my EGR valve and replaced them with block off plates from Billet Technology. Once unplugged, it will register disabled with a CEL, but can be disabled with the Diablo Tuner, which may come in handy with a new manifold setup. However with OBDII testing it will comeback as "setting failure." I forgot to enable mine years ago and failed an emissions test because of this, fortunately it was an easy fix.

Are those numbers with manifold based off a stock assembly? That's pretty impressive if so, the best I've seen was a polished and ported 6.1 intake manifold tuned fittef to a pre-eagle 5.7 pushing around high teens rwhp, and low twenties rwtq.
