I mean in the middle of what I imagine is a 100% WOT you are only getting 100%TP during spool or loading of the engine. How does the engine hold boost? Does it peak and taper off or does it stay flat? that dip from 3-4k looks almost as if the transmission is down shifting,because look at the second pull that dip is not there, but im just speculating I dont know whats actually going on during this log. I'm more interested in not getting 100% throttle through out the whole pull.

I find it improbable that it isn't electronic; these days, it's all that way. I can only speak of the "alpha" revision of it as updates for it are taking a while because the ECU is ridiculously complex. The engine holds boost up until about 5000 where it tapers off; my current power band is 2500 or 3000 through 5000. I suspect this is because it is a small turbo with a small displacement engine. Perhaps I'm misunderstanding, but this is all one pull.
