Gents, Corse ECU disables the secondary air injection system, but for your dyno readings not to be thrown off by the SAI, does it have to be blocked off? I won't bother at this point until I have the engine out eventually to remove the solenoids and block it off unless it's going to make the AFR/exhaust gas readings wonky. It just looks a little higher risk to try with the engine in than is worth if it's not a must (AF1's ad for the Driven plates warn that "engine out of frame installation is much easier" and "the three bolts that hold the covers on can be stripped easily.")
