if you did this the power level you would see might be somewhere around BOOM! you can use the belt and thats it. so yeah scrap the stage 2.

42# injectors (aka stage 2 injectors) are good till around the 260whp level (easy to acheive on m62)
the tune you cant use
the stage 2 pully wont bolt up
the belt you will need(can buy it seperately)

Anything past 80% IDC is considered "maxed" out as far as injectors are concerned.
The GM tune is pig rich WOT. Talking low 10's AFR.
Lean it out, and you can prolly advance timing a degree or two as well. change a couple other small tables and a "Stage 2" SS/SC with bolt ons could lay down 260whp.
