How much boost?

[Noisy]

I've picked myself up a Greddy turbo'd MX5, I'm going to take the kit off eventually and put it on my MX5, the car isn't running 100% though and I'm starting to look into what the issues could be.

Firstly I think I need to set the boost to the right level, it's got a greddy turbo kit, with baileys bov, saab intercooler, the vortech blue fuel regulator, what level should it boost too?

It appear to be lean too as the plugs are very white, is there any way to tweak it up with the kit I have?

The std kit come non intercooled and runs around 5/6psi.

This is what the fuel pressure regulator is set to support.

By adding an IC it is no longer a std kit and really needs a WB or R Road check to see whats happening.

6psi measured with an IC and 6 psi without an IC are NOT the same !

White usually means the plugs are running too hot. That could be because it's running too lean but given you're running FI it could also be that you need a cooler plug now. If you're setting this up yourself I would strongly recommend getting a wideband lambda sensor to make sure the fuelling is right under load, otherwise it's easy to damage the engine by running lean under load.

I'm going to get it on the rolling road soon, so will see what its doing.

How is life Pete?
