Hello. New here, but not to ST. Have had your systems on several bikes. I have a 2008 Roadglide with true duals, stage 1 a/c, SE Fatshot slip-ons with 10 discs and open end caps. Also a power commander V mapped for this set-up. I want to change to closed end caps. How many discs do I need to add to keep the same map? Please include P/N for the discs and your "logo" (402-3046?) end caps. Thanks, Bill
