Ive had a few problems getting the new manifold working properly.

I made it with the injectors mounted out near the ends of the runners. when i tried to tune it, it was nearly impossable to get the fueling right until the air speed was high enough (about 2500-3000 rpm). I pulled it off again and mounted a second set of injectors pointed at the back of the valves.
The primary injectors run at low speeds and loads and the secondary injectors are phased in as the load and revs come up. Seems to be fairly seemless.
End result wasnt much better than the other manifolds. Its a little better at a couple of points and worse in others.
