Super Smooth FP-4

By   on  Verified Purchaser

All I can say is, based on my limited experience with remapping my bikes, this device worked flawlessly and my bike is running better than ever!

Bike runs so much cooler now

By   on  Verified Purchaser

So far so good. Did a stage 1. This is easy to tune and my AFR is exactly where it needs to be. Bike runs so much cooler now.


By   on  Verified Purchaser

This is the 2nd fuel pak 4 I bought.

Always the best

By   on  Verified Purchaser

Always the best. Quick and easy to install.

Nice tuner

By   on  Verified Purchaser

Nice tuner, all good so far. Great value.

FP 4

By   on  Verified Purchaser

Works great after figuring out how to connect it. My bike kept powering down because my lithium battery. Hooked battery pack up and programmer worked great. Made a big difference in performance and especially initial take off.


By   on  Verified Purchaser

Very good


By   on  Verified Purchaser

Got the fp4, but had to send it back to vance and hines because of a bad bluetooth chip in the tuner. Received the new tuner an works perfectly.

What a Gas

By   on  Verified Purchaser

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

By   on  Verified Purchaser

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

By   on  Verified Purchaser

Would not auto tune bike, drops communication phone interface. Not as easy as 1-2-3.

So far it's been really good

By   on  Verified Purchaser

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

By   on  Verified Purchaser

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

By   on  Verified Purchaser

Took time to get it set up but working good.


By   on  Verified Purchaser

Good product.

Thumbs Up

By   on  Verified Purchaser

Working great.


By   on  Verified Purchaser

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

Easy to use

By   on  Verified Purchaser

Easy to use, plug and play.

Excellent service from V&H and Parts Giant

By   on  Verified Purchaser

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!

Vance & Hines FP4

By   on  Verified Purchaser

Had what I wanted in stock. Vance & Hines FP4 was cheaper. Thank you!

Questions & Answers

Ask Question

Will this work on a 2011 street glide

Yes, if you were to choose the 2011 Harley Davidson FLHX Street Glide FP4 Fuelpak tuner from our fit guide, you'd receive the correct unit to fit your Harley-Davidson. Installation is simple - barely a ten minute operation if you decide to eat a sandwich half way through removing a side cover! Just configure it accordingly using the free FP4 app on your phone and hit the road!

Answer Question

Can this item be programed for Bassani Softail FLSB system?

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.
