hi there, iv just purchased my self a2005 ba mkii xr6t and just havin a few little issues 1, when im givin it a bit of right foot on boost it will just seem to cut the power, I was thinking some sort of restricter but sometimes it does it at 3500 revs n sometimes it does it at 5000 revs valve springs have only just been done 2 mnths ago.... 2, this weird shutter ( iv only noticed it when the car cools down, as in if I drive somewhere then park it up for an hour the go for a drive it will do it again, only for 5-10 seconds) the car will stall if you dnt rev it, it seems like its not running on all cylinders. 3, clunking in the diff, or something in the rear. when changing gears the clunking is very noticeable but iv seen receipts from not too long ago the diff having some warranty work done to it.. any helpfull info would be great
