Super easy install and it works based on a boost tap. You’ll feel it more in the low to mid range but the app needs to be updated for better connectivity. The only issue I have had has been it disconnecting then reconnecting over and over. I think if they can update the app for a cleaner experience it would be great and would give it 5 stars. I have had no check engine lights or anything after a month of use. I use 91 oct

Installed app and tuner, definitely see a big change.....but had my utv go into limp mode and shut off? Turned everything off and restarted no problem? There is hardly any info on tuner on line another draw back ... install was easy once I found the plug .... and of course no instructions other a shot video that showed him plugging it in .. other then that was very easy when I found it ... I was also looking on testing of the unit. None that I can find..? Why no dyno. Test on YouTube? To show what it can do ? Maybe that’s why if it shuts the utv down.... Ok now the good ..easy to use app lol but no info how to use it . Not hard but should have something! It. Seemed to work but more testing of my own to see if it shut down agin ... it did break traction on pavement! Left a nice burn . But will need more time to play ...

Works with DINANTRONICS sport tuner and covers the only down fall of the d sport app which is limited boost gauge visibility.

I had this product for a few years now with no issues on my 2016 Ford Explorer sport with the 3.5 TT ecoboost. I must say I’ve loved the way it woke up the motor and performance. The reason I’m writing this review and giving it 1 star is because of the latest and most recent software update. I’ve had nothing but issues since it was pushed out. Check engine light coming on now, terrible lag with the boost and it even sent my vehicle into limp mode.also the boost gauge won’t work on the app . flowmaster why change something that wasn’t broke??? I’m seriously thinking about switching to another product that does the same thing with additional boost and then some fuel remapping . please fix ..
