Additionally, it is the most powerful, quickest, and fastest overall S63TU V8 in the world. Feel free to call it a triple crown.
What is the magic recipe? As follows:
Pure S1 Turbos
Flash + JB4/BCM + Meth
Upgraded DCT Clutch
27psi on 100-octane fuel
The flash plus JB4 piggyback tuning combo is working well. Obviously the Pure Turbos Stage 1 S63TU turbocharger upgrade deserves a lion's share of the credit.
139 miles per hour in a ~4300 pound car is moving. 10.153 is seriously quick as well. The F10 M5 now leaps ahead of all Audi RS7 as well as Mercedes-AMG E63/CLS63 1/4 mile passes. It also is poised to be the first to run 9's.
It looks like the M5 is the king after all.
