Customer service was amazing. I did not see the option to add the mods to my bike. I called them and they sent me the correct tune for my set up. Five stars all the way.

Back in 2017 I did SE Cam, quicky pushrods, lifters, air cleaner to my 17 Street glide 107 and Vance & hines FP4 tuner. Just couldn’t get the hesitation on slow start off (like from stop signs) emailed Tech support the very next day they sent me a custom tune . Installed it and Bam hesitation was all gone. LOVED IT. Traded bike in 2021 for road glide limited 114. Now I’ve done the SE cam ,lifters, air cleaner, pushrods. And purchased the power vision 4 based on what I had… I am now buying the FP4 and removing PV4 from my bike and hanging it on my was of learning curves (wall of shame) lol. The PV is about as user friendly as a wild mongoose. FP4 is for the consumer. PV4 is for shops!

After having a FP3 on my last bike with no issues, I decided on a FP4 for my 21 Road glide. . I have just recently upgraded my 114 cam to the 462 SE grind. First off once again customer service was top notch. Any questions I had were answered very promptly. Recently I rode with a few friends running a competitors tuner and larger C.I. motor and have shown a FP4 with a SE cam can run very well. Thank you Brian and your team for continued efforts and dedication to the product.

5 Stars… plug in, follow instructions and done! A single bike tuner that sorts all the issues you could think of regarding tuning to a V&H pipe(s). Super recommended. Now have to buy one for my wifes Softail Deluxe 2011! Awesome job V&H!

Got FP4 with Slash Cut Slip Ons and VO2 on my 21’ Iron 1200, very happy with results, easy to connect, flash map and tune/access information.

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!
Grant Petreikis –
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.
Sutoyo –
Good quality

Wow! No lag, no bumpy throttle, all performance! Easy install too! Highly recommend!
