I had a custom tune written for my Diablo Sport Predator tuner for my 05 to dissable the CEL. By the way it only came on occasionally, but got tired of resetting it on long trips. It was always a P401 but you worry it may be something else when your miles from home. As for the intake stick with the stock manifold, leave the EGR valve in place and connected. Also install freeze plugs in the EGR cooler exhaust inlet and outlets. Remove the scoop in the up-pipe and weld in a stainless plug.

Ok. I am doing arp studs and factory gaskets. I don't understand what you all are saying about the stock manifold... it is stock. The only thing I am changing is an egr delete from sinister diesel. How can I bolt a egr valve on top of the block off plate. Once again, thanks for the help and please keep it comin, im trying to understand what you're saying

I put the sinister EGR delete on my 05 about 2 weeks ago. I left the EGR valve in place and plugged in. I've put about 1,000 miles on it and no cel light yet.

Does that do anything good/bad besides krep the light off? Why does it come with a block off plate if you don't need it?

While your that far into it don't forget the oil cooler! Clean or replace, whatever your are comfortable with, Hope your project goes well.

if you are doing a true delete, and removing the cooler, and replacing the coolant pipe so it is going direct from intake manifold to oil cooler then there is no side effect from leaving the egr valve in the intake manifold that i can see, they all provide a block off plate for the top of the manifold, but i dont see any reason to remove it, there is mostly negative effects to leaving it unplugged

Having it unplugged messes with fan... correct? If so, how? And will it do what its supposed to even with the egr delete?

It was mentioned in a comment earlier in the thread that your intake manifold was welded. No need to weld anything on the manifold. The EGR cooler exhaust inlet and outlet will be blocked off with SS freeze plugs. They don't have to be welded either but welding the plugs gives a little more leak protection an peace of mind. Leaving the EGR valve in place and connected (do not install the Sinister blockoff plate) gives a totally stock look. Hope that clears it up for you.

If the EGR delete application was used for what it's really intended for and that's off road racing and by the way the only legal installation, you would use the block off plate. On the street you want it to look as stock as possible depending on state or provincial smog laws and regulations. Use the pretty blue plate with the Sinister logo on your tool box, wall or somewhere else. On your engine it's a dead give away.
