theory a: we're all a bunch of hacks (especially me!) and need to learn to let up the accelerator more / faster when up-shifting

theory b: conspiracy... syncro rev match "blips" the throttle even on an upshift

theory c: something else causing RPMs to run up in between gears, e.g., mass of trannie clutch et al released and so engine and flywheel free to spin faster... suppose this is typical, but is there anything about this car that would increase the effect?

anyone else had the same observation?

I think this may be related to the overheating issue on my other thread... rev limiter works - when the driver is stepping on the gas, it steps in- but i'm not convinced it will defeat the engine from accelerating over the rpm limit when the RPM overrun happens in between gears as described above
Theory b is correct. SynchroRev Match assists you even when you upshift. I was just as surprised back then as you are now. I was looking at the Quick Reference Guide and that's when I saw the feature. You can learn in detail in the following thread
