Stage 1 RENNtech A45 AMG on the Track, Dyno

We’re giving you a double dose of AMG action in this week’s AMG Monday Morning Wake-Up Call.

In the first video, check out RENNtech’s Stage 1 tune for the A45 AMG that bumps output to 414 horsepower and 393 lb-ft of torque at about 27 pounds of boost.

In the next video, the cylinder count doubles with the 762-horsepower Kleemann SLS AMG revving and accelerating with its sonorous Capristo exhaust system. An otoscopic examination of someone watching this video would reveal a tympanic membrane made very happy by this SLS AMG’s exhaust sound.
