Thanks for the input jmrtsus. I ended up going with Cobb AP/Filter through Mountune.Ordered the Mountune MP215 kit from Levittown Ford $1131 delivered. Installed by ASE mechanic for $150. So $1281.......total cost. Emailed pics of receipts to Ford and am good with warranty. The one thing Cobb can't do. Cobb is much more flexible but I want my warranty now. Maybe upgrade to the Cobb tuner thru Mountune later.
