It sounds like it was in a regen cycle. The ECM increases the boost a few psi to make up for it. Or maybe you're just in a good mood and was really enjoying the car
Heh, I figured a few would assume that it was just me feeling sporty. But I swear, I have a finely calibrated but, and this was way out of the ordinary. Regen cycle sounds most likely, but I really wonder how in the world the regen cycle makes the turbo miraculously lag-free. And it wasn't a case of increased boost, necessarily, beause it was the instantaneous punch it had at very low RPM that I noticed. I was driving with my usual zeal, and from 3:30 PM to about 3:40 pm, there was a HUGE difference in turbo performance and response. Before and after that time, it drove normally.It sounds like it was in a regen cycle. The ECM increases the boost a few psi to make up for it.

Yeah, temperature has played a big role in torque response in other cars I've driven. My previous car, a 2000 Mazda Protege ES, had wheel-spinning torque when it was cold, and was pretty much gutless before 3500 RPM when it was warm.Did the temperature change? It been colder or warmer today? That's the single biggest thing i notice on my car here in FL, where it'll be 45 in the morning and 70 by noon. That temperature range really makes a difference in performance and fuel economy.
FWIW, when I forced an active regen on 2 different cars/owners, one person said the car felt sluggish. The other said it suddenly felt more powerful. It could just be related to how they normally drive or personal perception. And some cars just feel a little different too.Today, while the car was fully warmed up, I noticed that, for about 10 minutes or so, the car became dramatically more responsive, as though the turbo suddenly had zero lag whatsoever.
On my 2011, in the top right of the screen between the gauges, it tells me what gear I'm currently in, while accelerating or decelerating in-gear, and when cruising, it suggests an upshift or downshift if I'm not it the gear it thinks I should be in for best fuel economy. Useful, I guess, but also kind of annoying because, in the city driving I'm usually doing, I'm almost never able to cruise at a constant speed. That woudln't be a problem, except the suggested gear always puts me at 1200-1300 RPM, where there's no boost to pull me up a few MPH, so i end up up and downshifting more than I need to just to vary my speed by 5 MPH.Shift suggestion on MFI?
I have a 2010 model, does that exist on my model year or is that a 2011 feature?
Totally appreciate the response, but I do want to emphasize that it definitely wasn't personal perception, or my mood, or anything else like that. The car behaved normally before and after the "event." But for about 10 minutes, it was dramatically different as described above. And the increased response was repeatable. I spent time probing the engine's torque response over and over, and each time found that boost spooled instantaneously at VERY low RPM.FWIW, when I forced an active regen on 2 different cars/owners, one person said the car felt sluggish.
