Could not be easier to install and get running. Has to reload program twice due to some bug. Called tech service, they were really helpful.
Great tech support

Anytime you can override the Harley computer. I had two FP3 tuners and wouldn't use anything else. V&H have great tech support.
Would not auto tune

Would not auto tune bike, drops communication phone interface. Not as easy as 1-2-3.
So far it's been really good

Had a little trouble getting the map for my bike because I went with S&S exhaust and intake but when I called Vance and Hines they got me going in the right direction pretty quick and so far it's been really good
Only been on the bike a few days

Only been on the bike a few days but it's working fine bike runs a lot better so far. Didn't have my slip ons on the list of options but you can call them and wait 20 minutes on hold and they will tell you which ones to pick. Haven't had time to mess with much of the other stuff like gauges and auto turning yet.
Working good

FP4 improved my 22 Street Glide very much. The Screaming Eagle tuner was lacking.
No dealer needed to do the tune. I win.

Excellent service from V&H and Parts Giant
By William H. on

I've been using the V&H Fuelpak FP3 for years on several Harleys and love it - the FP4, paired to an iPhone, not so much (installed on a 21 FLHTK). Thanks to the patient help of a tech at V&H I was able to get the unit paired to my iPhone and working, but the app is definitely not prime time.
Customer service from Partsgiant was above and beyond - I wanted to have the unit installed for a 1100 mile ride I had coming up and got it to me a day ahead of the date promised. Excellent!

Can this item be programed for Bassani Softail FLSB system?
By Anon.
I am switching the manufactured exhaust system to Bassani Softail FLSB for 2021 Harley Davidson FLSB Softail Sport Glide and I would like to be sure if app has Bassani Softail FLSB in the list to be able to program it for the proper working.
Thank you.
The FP4 currently has exhaust choices from Vance & Hines, Python, Harley Davidson, Crusher, and Bagger Nation. You could always choose a Vance & Hines exhaust from their selection that is similar to the Bassani exhaust or use the Auto-Tune feature to get it as close as possible.
