My bone stock 2012 Ultra limited has MAJOR popping on decel from 2400 down to 1800 rpms and surges at same rpms on steady cruise. Surge is most noticed in lower gears like slight uphill in traffic at 25 mph. (very annoying!) It's been doing this since new and seems to be getting worse. I thought it might get better with some break-in miles but it hasn't. Took it to dealer Friday at 480 miles. They verified it, checked fuel pressure, checked for codes, updates, downloads and even replaced the mufflers with no change. Said a tuner would definitely fix it but after spending $25,000 I would think I shouldn't have to pay more to get it to run right. I probably will put a stage one on soon but I don't want them to blame it for any problems. I'm waiting to hear back from dealer on monday after they talk to HD. Anybody else with this problem?
