Default Dyno Results with A/F ratio...
So how smart is the Benz ECU? Smart enough! The car's A/F was running conservative! And there is about 20 RWHP to be gained with a good tune.

As you will see with my attachments the car is around 12.5@3,500 and goes down to 11.60-12.0 close to redline! She was protecting herself all along. I had a GUT feeling the car was running nicely but this takes that little monkey off my back.

The tune was done on a mustang dyno (which are known to be very conservative) shown in the link below...

I made 291 HP and 286 TQ on my first run and little less on the second. The tuner said on a dyno jet it would read around 350ish on both sides. So ASP was about right on the 20-25 RWHP gain after you consider the intake.
