How do you trun up the boost on the legnum's?
I'm running 12psi at the moment, thinking of putting it up to 13 or 14.
Or is it best to buy a boost controller?
I have already got a reflashed ecu in the car.

Do you have a larger exhaust and decat? That will give you a couple of PSI. Other then that, a boost controller

It only got 3" catback exhaust but need to replace the muffler on it.

Boost controler all the way. Personaly I favour the electronic type as I find they have a finer amount of adjustment.

You could always do another flash on the ECU.

If you have the little restrictor pill in the boost control solenoid, you can remove that for a couple more PSI too.

Personally, I have a 3port solenoid driven by the ECU (which of course is flashed). I have multiple boost profiles switchable, but in the end I only use the top one and just regulate boost with my foot...

Get a decat, then look at boost controller IMO

Cheers guys, will look at a decat and reflash..

Who the best to see about a reflash? Any idea of the cost?
