Currently the flash will work for stock configurations and slip ons. Air fliters aren't an issue. Of course there are some with full aftermarket exhausts, and currently I'm not supporting that, though I do have a full Area P system waiting to be installed and then I'll do a map for the area p system.
I think the biggest Issue I've faced so far is the questions - set forth as assertions - by folks who have no clue about what they are typing. There are a lot of wives tales and internet lore surrounding the tuning of the c-14, and some folks want to held steadfast to incorrect information, probably because it's all they have had to date. i'm glad to answer questions, but I won't divulge specifics of my tune. Read the reports, don't take anything I say at face value, research it. Steve
