Definitely include me in once you get this thing going. The J & S Safeguard also kicks you into open loop once you go into boost. In my mind, it's most certainly a desireable thing. Although you may benefit from a tad more power with the ecu seeking out that stoich a/f ratio, I would think so long as you tune yourself to a good a/f ratio at a particular rpm/kPa, you should be where you want to be. I mean, if 14.7:1 is what you want, you could tune for it more consistently IMO.

But for me, it's all about safety. I would prefer the richer partial boosted condition.
