Wait a minute 
was it at 8 psi already? If it was then that's fine for a motor with stock internals especially if it's a t25, that's a f**kin small turbo yo. All I know is tho, if you make that rod bigger then you will up the boost. If you want to lower the boost you need to CUT THE ROD not add s**t to it 
even 10psi wouldn't be s**t with that small turbo, you can run that with stock internals fine just as long as you have it tuned
