I believe I poorly worded my post. I meant to say, the flange you bolted up to was a factory flange that used to have the egr short tube on it, from the factory.Yes, the gate will not fit with egr. But at that point you probably shouldn't have a cooler on anymore.
Actually, we used zero "factory stuff". That's a machined flange bolting where the egr used to mount. All stainless tubing and tig welded.
Why do you say not optimal? It's by far the best place to mount a gate on a stock 6.7. Anything else would be a giant pita to mount and get to. This fits without the need to change anything as long as your deleted. No different than a 6.4 wastegate that bolts on to its egr flange. They are widely produced/used on tons of trucks. This is the exact same principal.
we both know that a single gate on a single manifold that isn't at the end of the runner isn't optimal. Like I said, innovative and thinking outside of the box, which was a compliment.
I guess everything is taken in negative connotation anymore.
