Singh Autosport claiming to be the first to tune the 63 AMG M157 twin turbo V8, 600+ horsepower
Here we go again, for the second time
Singh is claiming to be the first to tune a motor without anything to substantiate it. We do know tuners have been working on this motor but Singh claims to be the first in North America to offer an upgrade. To substantiate this they have provided... nothing. No dyno chart as support, no customer impressions, no pricing, just a shot of the engine bay. We saw these claims from Singh previously and they were dismissed as unsubstantiated. We have to do the same here, but know that 600+ hp tunes are coming.
