Got it all finished up:
Took it for a test drive and this definatly makes it feel smoother when backing up, it would kinda studder as I slipped the clutch to roll back.
As far as the tuning goes, it has a nice amount of power now, so it feels like it can get out of its own way instead of being a giant turd. I do need to back off the pre boost screw just a little, rolling a little coal as I get into it, but then when the boost comes on it cleans up nicely and takes off.
