Hartmut Feyhl left AMG after 15 years to start his own tuning company, RennTech, which is now one of the most respected AMG tuners in the world. His products range from simple software upgrades to full racing builds based on AMG street cars.

The 1,100 HP Switzer "Ultimate Street Edition" GTR - /TUNED
It wasn't long ago that driving a 1000+ horsepower car came with
many sacrifices. These were race or show cars, not to be used daily. Enter
the Switzer "Ultimate Street" GTR. On pump gas, it makes 1,000 horsepower with virtually no
downside. On race gas, it makes 1,100 horsepower. And the owner of
this particular GTR uses it as his daily driver to commute to work. Is
enough to get to the office? We'll find out.

said tune is estimated to make over 900 WHEEL horsepower via upgraded
software and turbos. Yep, you read that
correctly. Now go watch the video!
