Upgraded app is sweet and easy to use. Got it for my 2006 Dyna Low rider. 2 into 1 Hairsplitter pipes with high flow intake. Flashed a base map that matched my setup and autotuned from there to fine-tune. Easy money. I will say their customer service freaking sucks and are rude as all get out. 0 out of 5 starys for them. There is an easy way to get around the California blackout on downloading tunes. 3 letters but yoy gotta use your brain. Good luck!!!

2007 Sportster - HD's first year EFI. PV4 installed effortlessly, Bluetooth connected and downloaded firmware and ECU tunes without any issues. PC modified ECU retunes loaded wirelessly using the cloud server. My questions with voice/email customer service was excellent.

Awesome tuner with excellent customer service. Way better than fuelpak. Night and day difference. Thank you dynojet!!

The app works fine, easy for beginners to understand. People leaving bad reviews are, understandably, mad at the very few tunes available. I'm just waiting for autotune to finally be available on android.

If you've bought a bike in California, no matter where you're at, you are screwed. Do not buy the Dynojet pv4, and I wouldn't buy one anyway because these people will not work with you at all. They totally blow you off and after spending $500. These people must be making too much money. So don't buy a PV4. Trust me, go buy it thunder Max. cuz all these people want is your money. Then once you buy it you've only got one tune, and then you've got to spend more money. If you want any more tunes.

App worked the first time I used it but now the 2nt time it won't even let me log in. I've deleted and re-installed it several times, called dynojet still no luck.

Cannot connect to my PCV. This app requires Bluetooth. Downloaded app to check the tune and cannot connect.

FIX THE ANDROID APP! I STRUGGLED FOR HOURS TRYING TO LOAD A TUNE AFTER MY BUILD UNTIL A FRIEND SHOWED UP WITH AN IPHONE! THAT IS RIDICULOUS!!!!
