components. but yes his psi should not be set at 15 w/out injectors. so 15psi on stock turbos and maybe? 10 or so psi on sport 600's. I don't think he will see much gain if any. he might just have to slowly adjst up until detonation and then back it down a little to get it set up right. I havn't heard of any one with this setup before so its hard to say.
