Finally got to road test my 08 Night Train after reprogramming the ECM, installing the Thunderheaders and the SE Air Cleaner. I noticed the new T-headers smoked quite a bit on the first start up, don't remember it doing that on my 04 FXDX. Anyway, rode for about 40 miles and didn't experience any popping during decel or between gear shifts. Checked front and rear plugs after my short ride...nice light tan color. I'm totally satisfied with the map I created.
I'll post some pics on the "who has a Night Train thread" later on.
