Mercedes-Benz->ke187 tuners in Germany are pretty much a dime a dozen, so many times we see just basic upgrades and overwhelmingly “blah” modifications. Fortunately, GAD Motors is one that rarely, if ever, puts together a “blah” kind of Benz. Its recent program for the CLS 63 AMG, which pumps out 563 horsepower straight off of the showroom floor, proves it.

This 4-stage program starts off with the Wattage V1 program, which adds in replacement, high-flow air filters, a mild boost in boost psi, remapping of the fuel and ignition systems, and a V max upgrade. This bumps the CLS 63 AMG up to 640 PS (631 horsepower), a 68-horsepower increase. This kit costs €3,000 ($3,841 at the current exchange rates)

The second stage is the Wattage V2, which adds in high-flow air filters, water-to-air intercooler with water pump, low-resistance downpipe with high-flow cats and a low-resistance exhaust system, an increase in turbocharger boost pressure, remapped ignition and fuel systems, and a V max upgrade. This is good for 670 PS (661 horsepower), which is an impressive 108-horsepower jump. This kit will set you back €8,600 ($11,011)

Stage three, known as the Wattage V3 kit, includes everything found in the Wattage V2 kit, but it adds in 30-percent larger GAD turbochargers, which significantly increases the overall boost. This jumps the CLS 63 AMG’s V-8 engine to a massive 730 PS (720 horsepower). That is a full 157 horsepower more than the 63 AMG made from the factory. The V3 kit will cost you €16,400 ($20,998)

The fourth and final stage is dubbed the Wattage V4 and includes everything from the V3 package and then some. The extra goodies on the V4 package include: boost increase and an optimized exhaust system – the exact exhaust specifics are not known. This jumps the CLS 63 AMG->ke8’s power to 800 PS (789 horsepower) – a huge leap of 226 horsepower. The V4 kit runs a grand total of €25,600 ($32,778)

There is no mention of what kind of track number this model can pull, but we assume a 0-to-60 time in the low-3-second range, maybe even into the high-2s.

On the outside, there are a few minor upgrades, including gunmetal-colored HRE wheels, as well as gunmetal-colored grille and side-view mirrors.
