Hi Kato,
Because cars vary in price I am reluctant to post a generic price. For example an STi does cost more than than a WRX, and a Liberty B4 twin turbo can take more time to tune as well. Other things which can affect the price include mods to the car. A CAI, bigger TMIC and
TBE will not change the price but a 3 port boost controller or larger turbo might. Lets just say that it is between 1/3 and 1/2 of the prices I have seen quoted for some dyno tunes.
