If there is enough interest / depostis for the tuning day then its generally $600/tune if there 5 people and knock at least $50 off of that per person for every 5 over that....

Don't quote me on that, like I said Greg or Tony at Eurocharged can give you exact details of how they want to set it up. The cost of the tune depends on the car also... some of the bigger MBs (the 55k, 63, and 65 V12 TT engines cost more).

$600 is what it costs for the 32 and 32k engine (M112 and M112k aka C320/SLK320/Crossfire and C32/SLK32/SRT6 respectively)

That is a starting point, but like I've said and will say again... I suggest going to Greg or Tony at Eurocharged. They can give specifics and clear up any confusion for anyone wanting a tune.

It may start out at a lower price point from the get go, but $600 is the most it would start out at for any crossfire/SRT6.
