You can try. When I had a bad exhaust set up on my TII I could crank it up to 12psi, but it would fall to 6psi within 2 seconds of reaching peak boost, so the extra boost was essentially rendered useless just because of restrictive exhaust.

What do you mean by "bad exhaust"? I would say you had other issues than just bad exhaust.

It was restrictive. As soon as I replaced the muffler that was in the middle of the system with a piece of flex pipe it boosted fine.

I guess everything has limits.
