Put FP4 on my 2021 Ultra Limited 114 with Rinehart slip-ons and Rinehart Big air sucker intake last year used a provided map off of the FP4 worked pretty good did a auto tune and made a huge improvement. Hoping V&H will add maps for stage 2 at some point.

I’m 69 years old and put a vo2 filter and 2 into 1 slip-on with fp4 on my 2014 switchback! Just watching videos made it simple! Thanks for all the information! Now it sounds like a Harley 😉

Installed after during the winter with no issues and great performance. While applying the auto tune I was running, I interrupted the upload and locked my ECM. Contacted customer service and they emailed a shipping slip to send the ECM and FP-4 and it was there within two days. A day after delivery the tech assigned contacted me to ask what I was running so he could modify a tune based off of what I was running. The ECM and tuner were delivered the following day (California to North Carolina) and it started right up. Bottom line; great product, better customer service. Extremely satisfied. Thanks Matthew!

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.

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.

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!

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!

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.
