Help tweaking a MMM.

[JAILBIRD]

I need some help tweaking my MMM. It's in an LST2 with a CC1717 powered by a 5k mah 6s pack. It has this strange little stutter on start-up, not when I turn it on, but when I give it some throttle. I don't think it's cogging because it happens when I give minimal throttle to a full trigger grab.

The only things I changed with the Castle Link was the LVC and I raised the punch control to 30%. Any ideas what could be wrong?
