I´m recieving my new 997 turbo in february and will fit a Cargraphic "powerkit nr 1", that is 544 hp. I heard that a lot of european customer upgrade the 5:th and 6:th gears to higher ratios for better top speed and fuel economy when cruising.
Anyone that tried it here?
9ff are offering kits in three different steps. Anyone that knows which ratios they are using? Have a workshop here in sweden that can do the work but want to know which parts to order.
