I have a bmw 328i, and found an advertisement for this throttle response booster. It claims it has 6 settings with the highest setting having up to 300% throttle response and the eco mode having -25% throttle response. This device seems relatively new and it costs $265. I was wondering if this is worth the money. Because I could save gas using eco mode and also have a little fun on the streets as well. If you have this already installed, tell me if it truly works, if not, I’d love your general opinion. Thanks in advance!
