My advice, for what its worth is leave the tune alone unless you want to start chasing power and torque, then better brakes, suspension, diff bushes, breathing, fuel supply etc. Point is, remapping for just a tickle is tempting but isn't worth it. The stock engine is a pearler and the tune is perfectly matched with the ZF and 95 octane. It's a pretty economical car for what it is (big, heavy and fast). Keeping the factory tune makes servicing and diagnostics easy as. These things stock will go hard all day and remain reliable.
If I was to change anything on mine it would be the fitment of the larger F6 Intercooler. Helps to keep the thing running cool and in its optimal performance mode.
