Will the .6 bar spring reach like 22psi? Or should I get like a .8 or something?

 

u need a boost controller. spring doesnt matter i think...

 

spring does matter you can only boost double or close to it from your spring raiting using most boost controller.

 

you should be able do it with .8bar spring

 

yeh i have a profec spec 2, right now with a .6 bar i can do like 15psi at 45% on HIGH. And its like 28% for 10psi on LOW. So Im not sure how high I can go, figure I should change before tuning so I know I can reach the #s
