New to the forum but have been following it since summer '09. I bought my 08 QP GTS in Sept after much research and searching for the right car. I was coming off of a MB CLS55 and was initially impressed with handling/styling, but power and torque was a little disappointing considering my previous car. After reading the forum, I decided to go the forumula dynamics route. I had Jeff install the ECM and DBW on my 08 QP GTS. I thought I would see a small increase in power and a little more throttle response. Boy was I wrong. The car is a beast now. It doesn't have the shear torque of the AMG but it definitely feels the same with the added responsiveness. Everytime I get in the car, it amazes me how much deliverable power it has. Combine that with the already great suspension on the car and you now have improved upon the best 4 door sedan on the market. The BMW and MB just is in a lower league to the QP. My 2 cents worth for those of you considering the FD mods. Thanks again Jeff!
