You need a boost controller to turn up the boost. What Greddy turbo specifically? Your Microtech Instruction Manual has everything you need to know about what screens do what. Read that first!

PS: I would not take the car into boost until you swap in the 1600 secondaries.

so the microtech doesn't have a boost controler?

Trav

nope

my dash mount from the microtech keeps reading 14psi, whats that about?is there a way of turning that down some without the boost controller?

Thats just a pressure reading. If you want have a lower boost, you have to switch wastegate springs.

I had been using a manual boost controller with my Lt8 before I sold my car. I built my own ball and spring. It worked great! Give it a try, but make sure you have enough fuel, and be sure to have it tuned before boosting much!
