i just got my g25 yesterday so i dont have too much experience but i did play with it for a few hours. I noticed that when UP-shifting you pretty much have to be COMPLETELY off the Throttle. But when DOWN-Shifting, you are allowed to gas/Rev for Rev-matching. It took a bit to get used to as i pulled a few miss-shifts myself. Only Gripe i had was when you miss shift you have to start all over, hit the clutch, put the shifter in neutral and then back into gear. Besides that it's a great wheel. If i shift as i do in my real car when spirited driving, it misses in the Game. But it's easy to get around it. Hope you're enjoying yours as much as i am mine.
