I need help. I built my own snorkel for my 08 rzr out of 2 in PVC and a k&m filter now it's not running right. Spits & sputters, too much air not enough fuel. Has anybody had any experience with EFI controllers? I am looking at this one wiseco rzr800 08-09 fuel management controller. This is what the dealer is telling me to do on it. What I need to know is how haefi controlerrd are these to set up? Any help would be appreciated.
