I've never tested a used sr20det and come up with more than 130~psi. They all ran fine, great even.
from 8.5 to 9:1 compression is so slight, you won't notice, the computer wont notice, nobody is going to notice. If you think about it in reverse, at 130psi the original 8.5:1 OEM compression is probably down a notch, and it still runs fine. So up a notch, down a notch, same difference.
