I have a street glide with high output slip-ons and the power headers. The included fp4 map for this configuration is awesome, but I sincerely hope for throttle response adjustment in a future software update.

The best tuner (and much more) out there today! You can monitor your bike, tune your bike, and tons more…. All at the touch of your phone!
This FP4 puts the power back to your wheel!

Amazing product! I was skeptical at first due to YouTube reviews and TikTok reviews, but I bit the bullet and went for it. Picked up a FP4 for my 2020 Iron 883 and couldn’t be happier. The bike feels and runs great. 10/10 would recommend. The autotune feature is nothing short of awesome!

FP4 made an immediate improvement to my 2016 Ultra Limited. I had a factory installed tune with my Stage 1 which seemed okay until I decatted the header, then there was nothing but popping & backfiring. That is all gone and the bike is more responsive, quieter and even a little bit more fuel efficient.
I am looking forward to an upcoming update to correct some readouts on my ios device.

While waiting for my slip-ons, did a “stock” tune on my stock 21 Heritage 114. Wow! What a difference. Smoothness, power, all on a stock setup. Can’t wait for my Eliminators.
