Renntech tuned W212 E63 AMG with the M157 twin turbo V8 runs 11.1@126 tune only on street tires
Low 11's on street tires tune only is an incredible achievement and exactly what a Renntech tuned E63 was able to do recently. This is now the new tune only stock tire record and was done in Florida at Palm Beach International Raceway. This E63 is the same car that ran 12.0@116 stock
. With just a tune it was able to gain 10 MPH and a full second in the 1/4 mile. Incredibly impressive and clearly a 10 second car on drag radials or even the stock tires in cooler weather.
