Renntech SLS Black Series before and after ECU tune dyno numbers
Nice to see a tuned SLS Black Series here courtesy of Renntech. You may remember last month a baseline dyno was posted showing an SLS Black Series on a Dynojet in STD correction which showed a baseline of 510 wheel horsepower. The Renntech Dyonjet baseline in STD correction shows 525 wheel horsepower stock. This 15 wheel horsepower difference can be attributed to 91 versus 93 octane as well as conditions, different dynos, and different cars.
So what did the SLS Black Series manage once tuned? 547 wheel horsepower or a gain of 22 horsepower at the wheels. Considering the high state of tune the SLS Black Series is in off the showroom floor it is impressive to see gains of over 20 wheel horsepower tune only.
