Need a updated list of ECU tuners for the C43

1.) Eurocharged
2.) OE tuning
3.) Renntech
4.) Kleemann
5.) Powerchip
These are the tuners I was able to find that did tuning for the C43. I went with Eurocharged (haven't tuned yet but have purchased the tune) as they have INCREDIBLE customer service, will reflash your tune for free, and offer a remote tuning cable so you don't have to remove your ECU and send it in to be tuned.
Eurocharged and OE tuning are priced comparably, Renntech and Kleemann are $$$$$$ and I wouldn't go with powerchip personally.
I would suggest you research the ones listed above and build your own opinion.

They said it takes about an hour or so

I had been looking at the powerchips site and they posted the before and after results of their programs for the C43, looked like good gains, something like 21hp and 27hp. They offered 2 levels of tuning, one was for 93 octane and other for 91.
It is a 'generic' tune to an extent, but my car will only will have res/cat delete and pulley upgrade, so i think nothing will be too off with their generic tune.
I dont see too much from the other tuners in terms of before and after results, but maybe i haven't looked well enough. But from what i have read it does not seem to be easy to find dyno results before and after eurocharged or Evosport tunes. thats what i liked about powerchips, they had the results posted right on the website.
also MB and BMW seem to be the biggest area of research/development for powerchip group.
here is the page for the C43:

i wont be looking to do this until spring as my car will be garaged for the michigan winter, but at that point im sure i will give them a call.

With the cable you could reflash in an hour
