W212 E63 AMG S 4Matic picks up 85 lb-ft of torque by going catless with a Eurocharged M157 retune
These are impressive gains on BenzBoost member @Cifnyc 's W212 Mercedes-AMG E63 S. He previously was making with a Stage I Eurocharged tune and meth injection 589 horsepower and 643 lb-ft of torque at all four wheels.
Well, he decided to punch out his catalytic converters, add a K&N filter, and get a retune from Eurocharged. The difference is incredible:
He picked up 39 horsepower and a large chunk of torque with 85 lb-ft more at all four wheels.
The green line is the meth pull which is just being used for cooling.
Impressive gains from ditching the cats and a new tune.

No im not tuned for meth at all, I chose not to tune for it. The retune was for the catless/gutted stock cats, plus a drop in k&n filter so it was returned to compensate for more intake air flow as well as more exhaust flow. I believe the timing was adjusted a slight boost was added. My meth injection is for consistency and cooling purposes only but I’m getting a power gain from my choice of nozzle placement which is a big plus.
