Here is something that may help the folks looking for extra power and the bad tranny shifting:
From bav auto parts
Got throttle lag? Put the punch back in your pedal and accelerate with confidence. The Sprint Booster power converter is an easy-to-install, electronic device that eliminates the delay in acceleration common in cars with Electronic Throttle Control (ETC, a.k.a. "drive by wire"). You get crisp acceleration on tap, whenever you want it, dramatically improving acceleration response time and your overall driving experience. (In other words, "Yee-haw!!!") It doesn't increase your car's horsepower -- it just make the car more responsive to your commands. You'll notice better off-the-line acceleration, faster 1/4-mile times, greater quickness when passing and easier on-hill starts. The Sprint Booster plugs in between the accelerator pedal and the ECM (Engine Control Module) where it continuously measures the digital signal being sent by the accelerator, modifies the signal and sends it on to the ETC, which tells the engine to respond more quickly. We tested it here at Bavarian Autosport and loved it! The installation took less than 10 minutes, and no modifications or changes in fuel are required. The first time we depressed the pedal, an instant smile appeared on our face... and didn't leave until an hour after we had climbed out of the car. Please note: There are different Sprint Boosters for manual and automatic transmissions -- make sure you are ordering the correct version for your car. One of the most noticeable performance upgrades you can do. Backed by a lifetime warranty.
It is supposed to reduce lag in drive by wire accelration.
Curious if anyone has used or has insight knowledge with this.
