I also had the stage 1 kit but wanted to upgrade without the fuel pump and stuff. I went to my local speed shop and they got me the jets from NOS for like 6 bucks.
As for the settings, I think that the stage 2 system is still set up for the 19's with allot of fuel pressure from the pump that comes with the kit. I had 30's and a 190 intank pump and ran with no problems.
