I just installed the Kleemann ECU Upgrade and pleased with the nice performance gain!

Bruce, Tuning Technology Motorsports in NY, was the dealer that I dealt with and he was extremely professional, competent and walked me through the process of removing/re-installing the ECU.

 

It was a pleasure being able to care of your need for more speed.

I knew the Kleemann tune was EXACTLY what you needed!

You are now my official ECU removal expert for the W212 in NJ!

 

What kind of performance gains are acheived?

I am taking delivery of an E550 Sedan next week and would be interested if there were something available for it.

Thanks

 

There wasn't a pre/post dyno done since Al removed the ECU and sent it off to Kleemann but Cory stated 20-25hp/tq and that would be at the crank.

Al says he feels quite a difference and when he comes to Long Island we will be putting high flow air filters in to complement the ECU file.
