I had the stainless akra headers with a brentune flash on my 20rr m sport, but I?m looking at the black widow headers with an rs2e flash for my new 21rr, has anyone fitted the black widow headers yet or have any experience with rs2e?
Brentuning is so hit n miss. Its not developed based on rider feedback and bike dynamics, just on dyno numbers. You need the handheld cause its never quite right. I doubt very much they have incorporated fuel cut tc.What did you think to brentuning? Any reason you are switching to rs2e?
