Renntech S65 ECU, Driving Difference
Just bought a 2011 S65. It only has 13K miles and still has a MB extended warranty through 2017.
I'm looking into the Renntech tune (only if it doesn't void warranty) and was hoping to hear from people who have it. Specifically on the difference on the driving experience beyond the increase felt when flooring it.
Does every day driving change as well?
Can anyone provide further details on the differences of before and after?

I had plenty of RENNtech stuff on my old car and it was well made, no complaints.
