New to Forum E550
We've had our E550 for about a year and a half now and it's a great car that's fun to drive, and I love the styling. My wife now wants an SUV so it'll become my toy. I'll definitely get it tuned and I'm considering a full exhaust bc I'll have to travel a good bit to have it done. I hope the performance gains will be quite noticeable, the numbers definitely look promising. After a tune, are the Eco and sport modes the same?
