Chipped / ECU tuned BMW E82 1M races a Porsche 997 Carrera GTS and pulls it
The 997 Carrera GTS is no slouch. It essentially bridges the (narrow) gap between the Carrera S and the GT3. With the PDK transmisison, it is a very quick car with its 408 horsepower 3.8 liter flat-6. The 1M is the slower vehicle stock for stock but all of us on BimmerBoost know how the N54 twin turbo under the hood responds to modifications. Well, with just a tune this 1M is able to make fairly quick work of this stock GTS in a roll on race. We are not sure what tune the 1M is running but the result is impressive.
