I am having a 07 335 M Cab, and heard of people replacing the chip for extra power, if this is done does it effect warranty etc and is worth doing, any advice welcome. Cheers
Hey dings, this is covered quite extensively in various threads, have a search for 335 flash tune type things and I'm sure you'll get plenty of answers (most being yes there are many tunes, and yes you will lose your warranty if they are found (which most aren't))
