Low end poping and cracking?

[Johndeere9610]

Is this normal for higher timing?

I'm running 25ish* timing.

180 pump 480cc of fuel
7x16's injectors set at p pump pressure
CR piston that are shaved and flycut and opened up a bit.
and haisley sled puller cam

Thanks

ive run 26, 28 and 30* on stock pistons and never had a low rpm cracking issue.

You may need a little more timing with that. Yes, I'm serious. Yes, you can call me. LOL
