Looking to get an ecu upgrade for my 2016 c63s.... trying to figure out if I want to go with Weistec of Eurocharged.
Renntech is out of the question. Looks like their numbers are very very low compared to the others.
If you are running any of the above please let me know.
I will also be ordering down pipes and would like some input on those as well.

I hAve had both Weistec and eurocharged on several different cars. Weistecs tunes way more aggressive and their customer support is 1000 times better. Eurocharged left my car disabled for 3 days cause their calibration guy was sick so I put the pulley on and they told me to call his number to log in and tune car and he never called but until 3 days later of me calling him atleast 30 times. Weistec handled 2 of my cars the same day and everytime I've ever had a question or an issue getting some body on the phone takes 2 min and my eurocharged tune my check engine light would come on and off occasionally and never has mine with my Weistec. The calibration guy at Weistec actually gave me his cell number cause I took the car on a Friday juts to make sure it ran good over the weekend. Their service is out of the planet good!!!! Ask for Alex over there if you decide to buy with Weistec. They are the best

thank you for the response!!
That is literally the response I was looking for.

Before you order call and talk to Alex and tell him Dave Adams referred you from one of the MBZ forums and he will probably give you a little discount. I send a lot of people to them and spend a fortune there and they always take care of me and my people

Hey,

RENNtech has yet to release official numbers for the 205 - C63 ECU Tune.
We plan on finishing our development this week, since we wanted to make sure to test and dyno our tune on as many cars as possible in order to provide consistent power figures.

We'll post a link to the official release here in the forum.
