I'm not sure about the Trinity controller. From my understanding they are not as adjustable as PCIII. I would call Trinity and talk w/ them. From what I've heard they are great to deal with.i bought my girl friend a trinity slip on and there efi contoler due to ajustability but im a carb man can i take it to an emissions place and put a sniffer in the pipe to tune i guess what im askin is how to find the perfect tune
