bought a tunit for the 335d just wanted to raise the output in line with the updated engine ie 313 and 465, went for the tunit as it can be altered to almost exactly those figures. I was going to wait until it had its first service which I paid for on the 3 or 5 year service plan, I drive says it needs servicing in 3700 miles but bmw say they wont do it until 1000 miles before the 3700 is up. so do I wait another 3 months to fit the box, id like to do it now but don't really want the hassle of removing it when the car is serviced or should I risk and leave it on. the o on the box apparently makes no difference to the standard power.
