Boost?? and Tuning
 

I just installed my microtech lt8 in my S5, and i'm trying to turn up the boost. how do i go about turning up the boost and what r u guys opions on tuning without going to a dyno. what screens do u adjust when tuning?

13bre motor
stock injectors
greddy t4 turbo kit
skyline intercooler
greddy power extreme exhaust
innovate wideband
walbro fuel pump

i have 1600cc injectors for the secondarys and areomotive external fuel pump but i want to learn the computer first on what i have. I'm just searching for helpful tips.

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?

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.

thanx man!!!!! how do u feel about the manuel boost controller? i would have to use that until i get more money for the profec b II.

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!

i have a to4 turbo in my car how do install a boost controller on the one vacuum line coming from the wastegate and can u explain to my on how u made the ball and spring?
