Ive got a greddy boost controller which i wanna remove from my 4x4. Ive looked but looks pretty complicated and ive no idea where to start. The car hasnt got an amal valve fitted i can see so is it a matter of getting one, and plumbing it in and removing the greddy one?

Would i need to get the boost looked at after amal valves fitted or will the boost be ok as it would have been set and simply controlled?
