weistec vs renntech for ECU tune on c63s coupe
As the title says which would you guys go with for ECU tune? I looked at Weistech and they give wheel horsepower totals that are respectful and Renntech gives motor totals which look great. not sure how theirs translate into wheel numbers which i would think they would post. I know my dealership works with Renntech so i probably wouldn't run into any warranty issues but does that justify the price difference?

I think that is a question that you need to answer. Is the peace of mind worth the extra cost to you. Also look into eurocharged. If I remember right they offer a warranty for the motor if their tune causes a catastrophe. But I would ask a lot of questions before relying on that. I'm not sure if weistec offers such a warranty.

The boss daily drives this car and we've had absolutely no problems with our tune on it. (All testing is done with this car.)

In my humble opinion:
There are other companies out there if you want the most power.
Renntech will never make a lot of power compared to the others, but their advantage is that they are dealer certified/approved.

No, it is not. Any dealer that installs Renntech is doing it on their own and covering any expenses on their own dime and is not reimbursed through MB like a regular warranty repair.

I see that about our the negative feedback for the one company stopped about a year ago. Seems like it was during a restructuring.
