Default Whats the difference between low pressure and high pressure spring?

Also, Are you running an MBC, N75, or EBC with your setup?

Default Running N75 only

Spring tells you how much boost you'll run off wastegate only.

Default What are your intended boost pressures?

What size waste gate are you running?
What engine size, how many gates?
What is the lowest boost setting that you can have? ( 1.2 bar spring, means you wont have anything less than 1.2 bar 19 psi or so. )
what turbo and AR?

The more details you have, the better i can help you choose the right gate.

Default why not run the lowest setting since the boost controller is doing its job from directing boost

to open the wastegates?

I'm just trying to understand how this works and how the spring pressure is relevant to the application

Default Mean Build!

Based on that and your overall goals, you will be set with a 1 bar spring. You will need to run more boost than 26 PSI to achieve 600 whp. you will have to roughly move about 79 lbs min.. and on a 3.0L it either means spinning it to ths stars, or ~ 28 psi.

Let me know when you need to order the TiAL Turbos and gates. The MVs is a 38mm Valve, V-band.
