glowing red manifold

do you have an air/fuel gauge? and yes that is not supposed to happen. My guess is the ecu wasnt seeing as much air as it wanted so it pulled back fuel, than you connected the charge pipe giving alot more air now it all out of wack. Thats really just an idea, I am not a MS expert, what are you running for air metering?

I have an M50B25 NV with an HX35 with a modified ebay mani. I'm also running COP MS1 V3.

I ran my car for a bit with the turbo loosely connected to the charge piping and it idled around 1000. After I hooked it up, the car started to idle around 2500. Then I noticed my exhaust mani was RED! I have a small exhaust leak so my O2 sensor is reading all over the place (could be noise too). I revved it a few times and it actually made 8psi at 7100rpms. That doesn't sound right at all.

Theories? Ideas? It's kinda scary to have your mani turn red at 2k rpms just sitting still.
