633 wheel horsepower S63TU - F10 M5 with Switzer piggy back tune puts down some big numbers
The last time BimmerBoost reported on the Switzer P700 package for the F10 M5 the car fitted with the P700 package cracked the 600 wheel barrier with a 604 wheel horsepower run on a Dynojet in SAE correction
. Definitely an impressive level of power but EAS (European Auto Source) recently tested an F10 M5 on their in house Dynojet and showed a peak of 633 wheel horsepower although in STD which will often read higher depending on the dyno conditions.
Additionally, this car has AMS catless downpipes which clearly are making quite a difference and an Akrapovic exhaust system. What makes this all the more impressive is this car is putting down the power on California 91 octane pump gas.
The tune is not a flash so there are pluses and minuses but there is no debating the F10 M5 is starting to put out some serious power with bolt on modifications.
