hi guy
i have comptech sc and i was wondering how many miles i have to change the pully belt caz i feel like the boost is lower than before, i have my boost gauge show that 0.5 using 7psi pulley but now it show 0.2 can it be because of the belt loose? thank you

 

Have you checked the belt? Did you try to turn it to see how much play there was?

If it's loose....tighten it....and see if that solves your problem.
