can the 900 guys tell me if a boss noss fuel controler is good or not. when I changed my fuel filter (it was so plugged I cant believe it even ran) it now has a bog in the mid range so Im thinking it might need to be leaned out a bit! does anyone have one of these controlers on there 900 and how does it work? is it plug and play or do I need to revamp something? any info would be great!
