    • AMG V8 showdown, M156 (M159) versus M157 - CLS63 AMG with PP-Performance Stage 2 tune races an SLS AMG with full exhaust

      We are going to be seeing many more M156 versus M157 comparisons as more and more owners of both of these motors modify them. This is a great race but obviously the M159 (based on the M156) V8 in the SLS AMG is at a power disadvantage versus the factory twin turbo M157 motor. The SLS holds off the CLS 63 AMG early on thanks in part to its quick shifting transmission but eventually the power of the ecu tuned CLS 63 AMG shows up top and it walks away. The SLS only has a full Supersprint exhaust so it does quite well considering the horsepower and torque disparity. If the SLS had some boost as well, say from a Weistec supercharger, the result would likely be quite different and in the favor the SLS.

        You know why you didn't know Joseph? It's because you keep posting false information without thinking. This loses credibility for you as an Admin. The same BS with the Renntech M157 tune. Your signature post is pathetic and doesn't tell the whole story. You see that video posted above. You will never see a Renntech tuned M157 doing the same thing. Go hang out with your moron buddy LZH. Try to get some sense and grow up you stupid douchebag

        Retarded doesn't even begin to explain it. Some people never learn and go through life wondering why they are always the victim. Hopefully he never has any children.

        agreed. lets keep it OT.

        Those m157 motors are retardedly fast. I used to think the M278s were the fastest things around..those cars use to slam me back in the seats.

        I have yet to take a ride in a new CLS but MB is gonna lay the smackdown on every BMW car out there and then some.
