when speaking of "positive boost pressure" i mean that throttle is open and the engine is sucking in air via the turbo. so in essence pre-spool starts from about 2200-2500K then i start to see positive manifold pressure at about 2700K and full boost at about 3200-3500K in first gear. sorry if i left anything out. i'll try a 3rd gear pull, but i'm pretty sure it's gonna be about the same. we'll see.
blackie: it could be closer to 4000K, not too sure because the needle hits so fast and my eyes are peeled on the road after that, it's too quick to tell, but it's around that vicinity.
