Newly built engine won't start
So I rebuilt my 2005 dyna FXDI. I put in a 97ci big bore kit with pistons, 79cc heads, 58mm throttle body, all S&S. Didn't upgrade the injectors or cams. I put a dyna jet power vision 3 and autotuner on it and flashed it with a 96ci Dyna 2 into 2 full exhaust with a high flow intake. My problem is it won't start. I turns over but I get nothing but flames out the tailpipe. Every couple of revolutions I get a snap that sounds like it's coming out of the intake. The engine makes no effort to actually run just flames out the pipe. So clearly it seems to be a mixture issue. My problem is That map is the closest there is to what is on my bike, so how do I fix it? Or am I wrong and it isn't a mixture issue and something else?

*update*
So I was double-checking my connections and found that I had the spark plug cables backward. Flipped them and it started up on the second crank. I was going through the break-in and it wasn't running for 3 minutes before a loud pop and it just shut off. It started sizzling and smoke coming out of the intake. I'm hoping that this is just part of the break-in. Gotta run it a few more times after it cools according to S&S
