thanks you too

Hi all! I'm new to the site as well as a 2011 Electra Glide Ultra Limited. I put 3500 miles on the bike and loved every minute of those miles. I was wondering if anyone could help me make a decision regarding putting a stage 1 air intake (screaming Eagle) Have Vance and Hines 4" High output Monster Rounds (Slip on's an) on the bike presently. I need some advise if I should do the ECM The Mechanic said he didn't need to put it on the dyno. I feel a little stupid at this point, any help would be greatly appreciated. Thx in advance
