Boost Controller

[Destero]

hey is it possible to wind the turbo psi 'down' from factory settings?

[fEkuaR]

it would depends on what the factory wastegate min boost level before opening is wouldnt it?

I guess you could try that boost solanoid trick? The stocker runs 5psi up to 4500rpm, then runs 7psi.

If you permanently ground the earth wire (I think it was earth, you have to read the thread), you could get 7psi always.

So I guess if you cut the ground wire, and never earth it, the ECU can never give it 7psi, and you'll be running 5psi constantly?

Otherwise, the TurboSmart boost controller that a user on here makes and sells is fully adjustable, and cheap.

this is not possible, the actuator spring determines the minimum amount of boost the car runs.

you cannot go lower than this setting, unless you change the actuator spring.

why would u want to ?

i'm pressuming this is on your r32?

the answer is no. you could fit a wategate from a r33 which is only 5psi instead of 10psi, but you will lose a fair bit of power.

are you wanting to put a turbo onto an NA car, and run a low boost/high compression setup? lol
