Default How much HP?

Hey guys, just got my FM II link put on. Am running about 10 psi right now. Was wondering what yall think I could run at 15 psi with a good tune? How safe would it be. I've seen some post where some of yall have setups running 15 psi and saying that it runs great. Going to tune the car a bit more and get it dynoed at 12 psi before I try to boost higher. I have a 94 NA with a brand new crate motor that has about 8k miles on it.

I've always heard 15 is fine...but if your worried, I'd imagine 12 psi would be fine?

With a good open exhaust and tune...~200-220 maybe if not more @ 12psi? <-that sound about right?

You think I could get around 260- 270 whp at 15 PSI. With a very free flowing exhaust, performance radiator, new plugs and wires. I have the Link ECU so I have good capability.

Plugs and wires don't add power... they restore it. If your engine only has 8K miles on it I don't imagine that a tune up will do you any good. 260-270whp from an FM2 kit is doable, but that really pushing the efficiency of the turbo (depends on wether you have the gt25 or 28 really). Is this their newest kit?
