All work great ### ⭐⭐⭐⭐⭐ Easy tuner for Harleys *by R***1 on 11 April 2025* Install of tune was so easy. Load app on phone and plug into the bike. Very easy and user friendly ### ⭐ An expensive paper weight with s l o w dispatch *by P***C on 17 July 2025* I rode 18000+ km on a stock 23 Softail 107 and am very aware of how it performs. Added slipon mufflers without any tuning and noticed a slight improvement in performance. Now have 20000km. Decided to do a full stage 1 by adding a high flow air cleaner and this frustrating PV4 device. Air cleaner install was simple and easy. First time booting up the PV4 all I got was error messages. Some time later after rebooting and resetting Bluetooth etc I finally got an error free connection. Flash the specific map and go for an 80km ride. Seat of the pants dyno tells me 2000 - 3000 rpm feels flat and lifeless now. This is the rev range I spend 99% of riding time. It was instantly responsive with plenty of giddy up on the stock tune. Feels a bit gutless now. The original grunty torque curve I loved has gone. Great, spend around $200 AU on an air cleaner kit, and nearly $800 AU for this dynojet paperweight that has made my bike run worse than stock. $50 worth of jets/needles, and an hour to install was all it took to do stage one carb tuning on my previous Harleys, always with positive outcomes. $800 (16 times the price) and a couple of hours frustration with this dynojet thing has resulted in a bike that runs worse, and instead of nice burbling when decelerating I now get random pops and bangs. Just got back from another 80km ride. The current tune has also created a dangerous stumble when moving off from stationary, twice causing me to nearly drop the bike. Right now I need to go back to stock tune and reinstall the stock air box and filter to get my original Better performance back, at least until I hopefully hear back from dynojet. Not holding my breath though. I do not recommend. Zero stars. p.s. I would not buy from this Amazon vendor again due to the slow dispatch and weird tracking. ## Frequently Bought Together - Dynojet Power Vision 4 `21-UP - M Maintenanse Air Filter Waterproof Rain Socker Protective Cover Fit For Harley Touring Flhr Flhx Dyna Softail Road King Heavy Breather Air Cleaner (117) - Oil Change Kit Compatible with Harley, Filter Cap Wrench, Crankcase Fill Tool, Primary Case Oil Funnel, Drip-Free Oil Filter Tool, 30Pcs Drain Plug O-Rings --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/633125434-dynojet-power-vision-4-21-up](https://www.desertcart.de/products/633125434-dynojet-power-vision-4-21-up) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-06-24*
