Okay so my friend and I both have Eurocharged Stage 1 ECU tuned W212 Biturbo E550’s. Both with primary and secondary resonators deleted while the catalytic converters and stock mufflers remained. My car is a 4-door 2015 4Matic sedan while his is a 2017 rear wheel drive convertible. Mine was tuned last August 2018 while his was tuned during the summer of 2017. We both use 94 octane gas from Petro Canada.

We drove each other’s cars the other day and I came away extremely disappointed to learn that his car accelerates like a BEAST compared to mine! It pins your shoulders to the seat back with incredible force far greater than mine and is so fast that it’s a little scary to drive.
I truly didn’t expect there to be such a great difference in the power generated by the same engines tuned by the same company with the same exhaust mods. I realize there is more power loss at the wheel for 4Matic cars vs rear wheel drive cars but not this noticeable. His car was far more responsive in all gears, had far more torque and just felt like a BEAST is the best way I can describe the overall driving experience.
Has anybody else experienced this or have any other theories why there is such a big difference between the two cars?
I'm gonna do a slight bump because I'm curious to see the difference in pulls between you two side by side....
Maybe your transmission needs to be reset, put the key in ON position (not car on) floor it, hold for 10 seconds, then release, then turn car on and it should be reset.
