Default Need a good starting point

Installed V&H power duals, Crusher slip ons, RSD high flow airbox, S&S oil pump and cam support plate, Woods Night Prowler 222 cam, SE adjustable pushrods, and a Thundermax in my 2019 FLHTK with a M8 114 in it.

Started with a Stock map for 2:1:2 and bike ran wonky for the first 20 or so miles and started dialing in. Issue I have is when I ride a while and she gets hot the idle will stick between 2.5-3.5k for around 15-30 seconds before it settles down to the 1000ish I have it set to. This is pretty hairy when I'm down shifting to slow her down.

Wondering if there's a setting I'm missing? I did look at the idle vs temp setting and it reads 1024 rpm across the board.

I'm baffled.

Your ECM ID making assumptions for engine load, cam timing and cylinder fill based on a baseline that has changed due to the cam change. You either need to find a base map for your combination or take it to a good tuner.

I would not ride it with the current MAP
