Ok, i just put in a Vmount, awesome, but i notice i don't get full boost until about 6000 RPMs, doesn't matter what gear. Before it would boost to 12 PSI (M2 ECU) but now it boosts about 10 unitl 6000 RPMS

I am thinking a boost leak. if so how do you find it, cause everything looks good?

one way is to spray brake cleaner around the engine while its idling, if there is a leak somewhere the idle with race slightly. Also you'll notice a pressure drop vs the smaller IC you had before (i'm going to assume it was smaller than what you have now) a 2psi drop is within the normal range i think.

yes i have a bigger IC, but why would a lose 2lbs of boost? Why do i get full boost but is now at 6k instead of like 4500?
