Just put the boattail on yesterday. I haven't driven enough miles to get a decent fill-up yet, but it sure drives differently. I normally coast down a hill, between exact points, and go from 55 mph to 52/53 depending on the headwind (always a headwind there). Last night I hit the coast at 55 and came out at 57 mph. Today, the headwind was fierce and I came out at 55. Definitely a longer coast. I'll have to do a test run soon. The temps are dropping a bit here in Jackson, WY. I'm hoping that won't affect the results much.
