Is it worthwhile buying a BS to run stacked with a Predator V2.02? I know that the Predator increases boost levels, so is it worth adding the BS?

i thought it was the best addition i made when i was running the 2.02.

I run the 2.02 with a boost stick and it's great. Definate improvement over just the 2.02 alone which only increases boost by 2-3 psi observed.
