as far as your temp gauge is concerned , you might just have a gauge problem ,or possibly a locked up fan clutch ,which can also cause engine drag
and less mpg , easy way to see if butterfly on back of turbo is causing your mpg concern would be to unook it tie it open and see if that akes a difference before buying or replacing anything, also do check that clutch fan
