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 can provide my experience to-date is poor with RENNtech. Run, Forest, run!

Hah! Can you provide some specifics as to why your experience has been poor?

Sincerely,

Wow - I never had issues with any of my RENNtech stuff (years ago, though).

Curious to hear the problems as well.

So, used wheels don't balance well and a CF lip has some tiny bubbles?

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

Haha! Erik, you so funny...

Yeah, thats what I did. Bought used parts and then want to whine about the quality and lack of customer service. Por favor.

The post said when you received the car. I assumed it was used. My fault.
