OK, I get it, now that I think about it, you're right, these two devices basically work opposite each other - one only lets pressure through UP TO a set pressure, and the other lets NO pressure through UNTIL the set pressure is reached. Makes perfect sense.

The EGTs were not bad either topping at about 800 degrees with the amount of fuel available. I never set the IP for more fuel.

I am going to duplicate this setup in the SDL.

Now THAT's what I'm looking for. I'm not looking to make mine a tire-smoking fire-breathing dragster, but if a little more performance is readily available at a small cost with no major economy hit, I'm all for it. It didn't ruin your fuel, economy, did it? Did it improve your boost at lower RPMs? Make the boost come on any earlier?

I have a air pressure gauge that will work well for a boost gauge, and a dual pillar gauge pod, now I just have to get a pyro, and one of these controllers and I'm all set. Thanks for the feedback!
