The same guy I bought the 99 SSEi from a local freind of mine who has over 10 bonnies.
Just looked on Ebay I have the right SC installed.

You get over 10 psi?

Any chance of you getting a scantool on it?

All I know is it goes as far as the stock gauge will go.

Above 10? It goes above 10. Or does it stop at 10?

It goes past 10 as far as the gauge will go.

Possibly 94/95 rotors in a 92/93 case. If this is true, it'* bad news.

So you're showing more boost than you did before? But less power.

No same boost is showing. Just noticeably less power. I also fixed some vaccum leaks. Maybe it was overboosting before.

If the rotors are shiny, they are either clean 92/93 or stripped (a no no) rotors from a 94/95. Stripped rotors would cause lowered boost.

But.... your boost is too high if you had stock stuff on before. Clogged cat maybe?

No Cat at all

Get a cat on there. It is highly illegal not to have one and is punishable by law. You need to obtain a scantool and see what your parameters are.
