Lightbulb pump tune for new injectors

Just installed ddp injectors and a Denny T2 fuell pin. My pump setting are star wheel bottomed out, smoke screw in 1 turn. I'm think I should turn the star wheel up to stock or higher, smoke screw back out also.What are the masses doing after such changes?
Full fuel screw is in a rew turns also.

I've moved mine all around. I ended up at 4 turns up from the bottom. My smoke screw is backed all the way out and I've got a little more clearance on the top for the cone to come up further. I don't have a fuel pin like you do though. I've got my own that I made. And I've shaved a little off the profile pin. My load screw is sitting just a hair less then 2 turns. And even with that I can suck my lift pump down to 7 psi under a full tilt buggy 4 gear run.
Good Luck with those sticks. I love mine!!!

I had better get a fuel pressure gauge to keep an eye on fuel pressure.

I've got my starwheel as far up as I can get it and the smoke screw is all the way out.

Star wheel flush with the top of the threads and the smoke screw all the way up with a spacer to lift it further.

Everyone's tune will differ even with a similar set up. It's a mater of how soon you want to get there and how much smoke you need to hide it.
