i am only running five pounds of boost in my ls and it seems to do good i have all stock internals and slowmotion - the place that did the tuning - said with my mbc not to go over seven because anything greater could be detrimental later on down the road but if i were you i would do boost and build another engine on the side then boost it when your done it's a win win situation lol thats what i'm doing
