Hey All !!

I'm John and I just bought a 98 legnum. I want to get a bit more grunt out of it (dont we all ;-) I was thinking a boost controller would be the easiest way. What PSI boost do they run as standard ?? Also what PSI can I wind it up to with a controller without having to modify anything else or worry about breaking something??

Factory around 8-9 psi can wind to about 12-13 psi without too much else but that will also nearly be the limit of what the turbos can produce...and before the moderators hound you, try the search function at the top first .People get sick of being asked the same question over and over and they dont realise that some people are unfamiliar with forums and that there is such a thing as search buttons..

If you wind the boost up like I have and also keep the stock Blow Off Valve this is what I'm getting. It will spike to about 14psi then sit on about 12psi and drop near to 10psi at high rev's as we need to get the metal EVO MR BOV as the stock one leaks under higher boost.

So a better BOV should hold boost a lot better. 10-12psi is probably about where you want it.

Fuel cut hits in at 15psi
