If your thinking about purchasing, I did last week and it is a HUGE difference. I watched all the videos and you can't tell, but once you have it installed you can I'd say it feels 1.5 times faster then before. My 2 cents.
Hi Eric, I have done hundreds of these 900 G4 tunes and have not heard of anyone having issues. The power level and rpm that the motor is run at is well within the engineered limits of the ProStar 900 engine. Our 2015 900 Crew that you see in the video has logged almost 3000 miles with this tune setup and its running as strong as ever. If you have over 2000 miles on your machine you will want to make sure your clutches are in good shape before installing the clutch. If you bring your machine down to us I offer installation of the clutch kit and tune your Ecu for $500.
You can buy the just flashed ECU or with clutch kit. you will not get the full performance without the clutch kit. Its very simple to change. 1 spring and 3 weights. Basic skills. I did both . My ranger is a totally different machine now. It sounds and runs like a RZR and has no Jerky takeoff. I use mine to haul and work also. The Kit is cheaper on Ebay. Hope this helps you out .
