No disrespect to anyone doing ECU reflashes. I personally don't know anyone running one on the hill. The Evolution kit has been in the works almost a year and was designed, tuned, and built for mountain riding. That's where I would put my money. Regardless of what setting I have the boost set at I have never seen more than 21lbs on the guage. The huffer is just maxed out.
Yes, it is the only reflash/ECU that was researched, dynoed, developed, tested over and over again in the mountains, specifically for the mountain rider. A lot ot time has been put into it and it works.
