Also, make sure that you are buying a tune from the person who actually wrote it. Paying a tuner to tune your car does not entitle someone to the right to resell that intellectual property to another individual. The payment is for the service, not for the right to reproduce or share.

 

What about if a tuner (and the only one whom supported it) stops writing tunes for your particular car?

I would prefer to not just have a massive part out sale.

I found mine for 42lb injectors and stock m62 with 2.2tb. Also have one that will do 60lb injectors and 1bar on a 2.4 tb. Currently I can't do more than 14.5psi safely.
