I have a stock 2004 Coupe F1, I had more that my share of issues with my car in the 22 miles I added since early May. After 5 weeks of waiting for the dealer to install a new f1 harness I got the car back Saturday.Today ( Tuesday) I had some time to not only start it but add a few miles. I went on a local straight almost never used backroad. I was at 3.5k rpms in 1st ( sport mode) and hit it,I shifted each gear at about 7200 rpms ( Only till 4th) Very hard to believe this engine only has 395hp. For a car that weights close to two tons with gas and a driver to pull that hard makes me think the factory underated the output. Feels faster then my old E55 which, I think had 456hp and weighted about the same. Today was the 1st time I redlined any gear with this car let alone the first 4. The most fun I will have all week.
