Heelo everyone, I have a 2005 nightrain, its has samson big guns exhuast and a stage 1 a/c kit on it. Thr front pipe is ok, but the back pipe is turning colors on the heat shield, so I know its running lean back there. I want to take it and get a tune or a check on the current tune. If it has not been done what programmer should I go with, our local harly dealership wants 1000.00 to change the mapping and dyno tune which is flat out crazy...

 

ok, Ive been looking at this SEPST? what is this? A programmer for a pc to reset the mapping? To due this at home or will a dyno be needed??

 

You can buy a power commander and tune it yourself using a map from their website and a laptop if you got one.

 

ask in the fuel an exhaust thread,sounds real high,tune and dyno..around $400
