FP4

I just did a stage one on my RG3 - 4" Tab Bam Sticks and a DK Customs High Flow 606 Air Cleaner. I also bought the FP4 to tune it. I wanted a user-friendly, EPA-compliant tuner that would not void my warranty. When I look at the available maps in Demo mode, I see numerous exhaust manufacturers listed and many maps. I emailed V&H for a map recommendation, and they gave me one. I see it in Demo mode, but when I connect the FP4 to my trike, it shows only one map - not the one recommended by V&H. I will call V&H tomorrow (today's Sunday), but this is driving me crazy today. Does anyone have experience with the FP4 and can offer some insight? I hope I didn't make a $500 mistake.

This is a follow-up to my original post. I contacted V&H customer support via email. They responded promptly, confirmed my trike upgrades, and sent me a map. I flashed the map and went for a ride. The trike seems to run great. I'll take it out for a longer run in a few days. I'm very happy with the customer support I received.

I put the FP4 on my 2007 Harley Softail. I used their canned tune in the beginning, then ran auto tune for about 150 miles. I picked up 2 MPG overall. I'll probably run it one more time to get it dialed in a little more.
I bought the Tuner to correct a running lean issue from the previous owner installed Vance and Hines exhaust system
