I've had the BB for at least a year and love it. My G26 died one too many times and I sold it and bought the YS. Trouble is I've burned almost two gallons trying to get it to run right. Every time I reset it to factory and start over it acts differently. If it did the same thing each time I would say, OK it's me, but it doesn't. One time it will die soon as the glow is removed. Next time it will not transition, next it will but dies when returned to idle. I've tried it all. RVator and I can't figure it out so I sent it back to YS performance. If they tell my they got it to run without actually changing anything, I'm selling it. I have one on my Mayhem 3D and once they took it and did something to it, it runs great. I've never done anything but set the top end and the idle with the trim.
