Hello. I just bought a 2008 Nightster and it has the Samson Slasher pipes on it. It has stock air filter and stock ECM with no programmer. I have figured from research tat I probably should get a high flow airfilter and also a tuner to program the Air FUel mix. Does anone have samson slasher pipes on a 1200 sportster or better yer a nightster? I am trying to find out what programmers have a map for the slasher pipes. I can't seem to find one. Fuelpak doesn't have any Samson maps for the sportster bikes...weird. Not looking to spend the dollars for the Power Commander 5 / Autotune. I have that on my softail deluxe, but it was expensive. Any ideas greatly appreciated! Thanks!
