I have a 2013 Deluxe with a Screamin eagle filter and V&H True Duals,no baffles. When I bought it,it already had these parts(yea lucky). It had the HD Flash upgrade to the ECM. It ran very good. I recently bought a PC V from another member here. I downloaded the map for SE air and tru duals on it(took ten min) I dont know **** and it went smooth. Plugged it in the bike (took five min). And wow the difference is big. It runs better,got more power everywhere. Mostly notice down low,but still big change everywhere. Smoother,cooler,More hp,torque,deciel pop is gone. Still has the raspy bwwwaaa but no pop.

So if you have uncorked your bike and think the HD flash was good, dont be fooled. There is a ton left. Go get one of these things now. It really is like riding a new,better bike... For my $165.00 this is by far the best thing yet!!
