Wow the new FP4 fuel tuner has such an innovative new look in the app and the LED lights are so simplified now my tiny motorcycle brain can understand them thanks Vance and Hines for making this so easy to use for us riders who don’t like complexity or new technology and the smaller thinner size is truly groundbreaking who cares about performance when it’s a fraction of an inch slimmer genius design it’s not like we mount these out of sight anyway and it’s emissions compliant everywhere but California which is perfect because what self-respecting Harley rider cares about California I’m sure Harley fans will love it and say it transforms their bike even though it seems overpriced with only minor upgrades from the old models but at least the customer service is good so I’ll stick to my cheaper tuner that does the same thing but good job Vance and Hines on selling new technology to buyers who don’t care about technology give me a break.
