Would fitting a breather kit lower my boost? Since fitting it my boost has dropped from peaking at 20.8 psi to 18 psi. only other thing ive fitted is a ACT Gauge which is tape`d into the inlet manifold.

Checked all the hoses and there all tight....would the turbo to air box hose do this if it was kinked?

 

dont think so, only the idle i think.

is the act leaking its only a shitty plastic connection isnt it, try putting the old one back and see what happens?

 

the samco's do have a slight kink in them i trimed mine down at each end to take this little kink away! tho i doubt that is the cause of the problem! could be anything that has happend since fitting breather kit! maybe just coincedence

 

i also noticed that kink

 

Yeh i did trim that hose so the kink wasnt there ..

So if there is an air leak on the idle screw or Act gauge bit that would loose boost?

Its almost like i have turned it down or sumat on the blitz boost controler..
They have 4 channels

1 was set at 8psi
2 15psi
3 20 psi..
4 about 21 psi


But now chan 3 is only peaking at 18 and drops to 17.



So could be actuator that over a yr old. turbo is 100k old lol..
