Hey Waterdog, Many "thanks" for the return response and the heads up info you were so kind to pass along.I'll check it out.I'm definitely replacing the stock pipes and the stock breather, and my H-D Dealer said I would need to have a re-map if I made those changes. So, figured I may as well go ahead and get the EFI tuned in line with the rest of the replacements and get eveything "working on the same page" so to speak. My H-D Dealer also said that the Screamin Eagle Stage 1 kit would much easier and better to tune to my new pipes and the SERT EFI System, rather than the Arlen Ness Stage 1 kit. Not sure about that , he might just be trying to make a sale on his in-stock equipment to reduce his Summer inventory? I'm still doing some more asking and researching. If ya hear anything, send me a line will ya? "THANKS", Ride safe, HI-Tek Rednek
