Having finally broken into the ECU set, AMS Performance is putting together a tuning package that will set your M5's wheels on fire with the help of 643whp and 606 lb-ft.
In case you're still doing the math, that's 93whp more than a stock M5 and over 100 lb-ft of bonus torque. This is still a work in progress and the car they tested on had already had some aftermarket work done on it such being fitted with AMS/Alpha 90mm non-catted downpipes, full Eisenmann exhaust and GruppeM airbox set.
So if you're good with a dynograph, the blue line is the car as it first drove into the garage (with a stock tune) while the red line represents hp and torque after the mods took place. Green line is a factory stock BMW M5.
While the overall gain in power is nothing to laugh at, the maximum torque output of 606 lb-ft (821 Nm) will give it that extra mid range grunt it needs to take on the likes of the all-new Cadillac CTS-V. In fact, we might have just found the perfect specs for an M5 if it were to go up against the CTS-V, otherwise it kind of ends up fighting a losing battle.
For all you autobahn speedsters out there, know that the limiter has been removed, however there's no word on how fast it will go now or how quickly it'll reach 62 mph compared with the 4.3 seconds a stock BMW M5 can manage.
