In this video I go over some basic questions regarding an ECU tune on a high performance car. What is it? Where do you get it? And what are some of the companies offering it to the Mercedes AMG platform. I do a quick comparison between Renntech and Weistec the two companies that I was debating between although there are over a dozen companies that offer tunes for this car. It all boils down to reputation and personal experience. I have had a great experience with my tune and I wanted to share that with others that might be debating between companies themselves. And at the very least I wanted to answer some questions about what exactly a tune is. I explain that is is software and not hardware. I decided to go with the Weistec tune and I go over the reasons why in this video. I hope you guys enjoy and I can't wait to continue this adventure!
