I'm not familiar with the OBS's, but if you can't find any boost leaks and your only making about 10-12 lbs. of boost, do you think your wastegate is opening up to early or do the OBS have a wastegate since there a bigger exhaust housing then the SD's?
My other truck I had, the wastegate was weak and wouldn't only make about 5 to 7 lbs. less boost then should of b/c of the it opening. Wouldn't it get hot if it opened to soon and ran there?
