Since I get a lto fo tickets (6 just since last December) I have recently just stuck to 2.5 BMW engines and have two 04's one 325 and 525. I enjoy loading the car up with features till it costs more than the models with bigger engines. But finally I think I am ready for some more power... However, I would be taking a hit of around 10K if I sold my two cars and got newer ones as I drive both of them a lot.
So, any suggestions on enigne microchip reprogramming and so on.. Safe, easy Horsepower upgrades for my 5 series?!
