First time down the track

The combo you describe sounds like a 450hp combo to me. But obviously you’re falling short at the track. Your total timing seems like a lot to me. Mine likes 34 degrees and not a bit more. It starts to fall on its face after that so I wonder if yours just has too much timing. Pull the timing back and see what it does.
You think that timing could cause as large as a disparity as it seems there is?
