Hi guys,

My car has a Greddy EBC(old version), recently I noticed that It's only hitting 22psi while the car is tuned at 26psi. Fuel to Air at 11.3 and its tuned at 11.5-6. I decided to crank up the boost and test again. Moved it up 3 clicks, 5 clicks, 10 clicks and boost stayed the same...

Then It hit me... The boost controller used to do A LOT of clicking/ticking noise before and know it's super quiet. I wanted to know where should I start to check to find the problem? Thanks in advance!

 

 

I would first start with a boost leak test... after that not too sure I am ecu controlled.
