Are you really claiming +47hp and +32 TQ (peak) with just an ECU upgrade for the M113 non-supercharged 5.5L engine?

Please post before/after dyno curves.
thank you

Why do you ask about M113 non-supercharged 5.5L engine ? It is written M156

My bad, I forgot this forum was also for 6.3 models and didn't recognize the m156 engine code.

dyno graphs would still be interesting to see, those are big gains from just an ecu tune!

Does this require special mechanical knowledge to install or is it basically plug and play?

This service is a flash performed directly to your ECU, so you must remove it from the car and reinstall yourself. It is very simple, and we do have a guide! See here for instructions:

On average the gains that we see coming from 100% factory to tuned with headers on a CLK Black would be about +60whp and +50wtq on 91 octane! The headers make a huge difference.
