So I made the pro tune and the tuner told me that he could not hit more than 1.3bar, he thinks that I have boost leak or the turbo is not in his best.
I went home and start investigating and that's what I found.
First off all changed the tmic from Chinese one to sti one, found leak in the intercooler lines and fix that, and replaced some vacuum lines that looks little bit worn.
After all those things yet I could not hit even 17 psi for a second than it drops to 13.
Checked again today for leaks and found nothing.
So now is the question where is the problem?
I'm with 3 port grimmspeed bcs, and read that the duty cycle should decrease 30% from the OEM bcs, which mean that if the OEM duty cycle is on 50% I should decrease to let's say 35% or raise it to 70%.
Now my max duty cycle is on 85% after the tune.
Tomorrow I will try driving without the line that goes to the wastegate to see if the turbocan rais the boost to 19-20 psi.
How to continue after ward?
