Hi all,I've recently acquired myself a brand new F10 520i due to temptation from the looks and the technology that made it. It was just a sudden purchase and I didnt have the time to find out more, other than opinions from some friends and the salesman. Overall, the car is pretty damn good and there are many things to play around with, like the Comfort Access Package, paddle shift m-sport steering, connected drive, dynamic damping control, and many more toys.However, after reading many of their brochures and marketing materials on how smart, economical, efficient, and powerful their new N20B20 engine, i simply took the plunge and bought myself one. The earliest stock that they could get their hands on was a 520i, so i just took it. I wouldnt say that i'm regretting, but a little disappointed. However smart and efficient the engine is, even with the 8-speed paddle shift gearbox, I find the power and acceleration is just too weedy. Yes, I know it may be more than enough for most people, but having an E46 330i at home, I cant help but still drive the old car most of the time. Even my wife's Lexus RX350 feels so much more powerful.So, here comes my question. Can anyone recommend any good power chips to boost the power? Of course I'm not expecting the same performance as my 330i, but at least 200-220hp would be great. I dont want to void my warranty by replacing turbos, or any major modifications. I know I should have waited and get myself a 528i instead, but its too late now, and I dont want to trade in or change the car. It has been only a month of ownership, and I'm looking for more power. My 330i gave me satisfaction for over 2 years before I started to upgrade the engine power, and that was purely for the fun of it, as the stock power was more than enough during everyday use.Any other recommendations and how I can squeeze more oomph from the car? I hope the "tai kors" of this great forum can help me out.
