4.0TT E63S AMG are the new heavy hitters of the big sedan market. Modified by BrenTuning they can see 620-660whp and 740-775wtq with just tuning and exhaust depending on fuel. Coupled with the new 9speed and twin scroll turbos this year makes for a fun package. While older Mercedes didn’t have a ton of top end feel when these are turned up they give you the sensation of a big single Supra or tuned Mclaren with their torque hit. Definitely on our wish list this year. Contact us today to get more out of your AMG platform.
