yeah this bloke said about changing the transfer box. The tyres I've got are only insa turbo special tracks (dont know what size they are tho - Brian will know, he's like google!! Chris I gues you loose a few mpg cos it's an auto but think of the luxury of not having to use your left leg ))What size tyres you got?
Mr Noisy is or has changed his xfer box to a higher ratio so it brings the revs in 5th to a better level and also helps with crawling
