I'm running 6psi right now in my civic(greddy turbo/intercooler). How kind of gains can I expect going to 9-10psi? As far as hp and 1/4 mile gains? Thanks

it will be a fairly big increase in power that you will feel seat of pants. Plus by adding a boost controller, it will keep the wastegate closed until its desired opening point instead of slowly opening of it before until desired boost.
