right, the car ( 2wd saph cos) normaly runs 18psi ( peaks at 20psi ) but since this morn it only running 12psi, y could this be?

it used to give a good kick back but nor the lower boost is gradual. help, i dont like it

 

amal valve playing up?

Boost leak, check the hoses

 

gona check the amal valve tomo, there defo no leaks tho.

the thing is it happened last night for a bit but then went back to normal, then it happened again this morn and hasnt changed

 

amal valve seems to be fine



bttt

 

block the feed to the actuator? let it overboost, see if it still falls.

did it on my ol silvia engine.. peaked at 18psi b4 falling back to a miserable 6psi ( damn those piddly little t2's ) lol

 

done that now and it dont fail. goes off gauge @ 30psi and drops and holds 26psi. plugged it back in coz it aint gona be healthy.


so im beginning to think it the actuator

anyone
