need advise, boost is only 0.6 on the second turbo last week and this week its only 0.4 / 0.5. Any ideas why?

Do i have a leak, if so whats the best way to find the leak. I have owned the car for 3 months now and did realise one of the boost hoses isnt going anywhere and is blocked by a bolt? is this normal?

oh mate your in for some fun - I have been having a simular battle with my controller install.

 

What pipe is missing and I need to know what exactly is blocked off - also do you have a boost controller?

 

Let me know and Ill be able to help :)

 

Things blocked with bolts often mean the system has been modded either crude or properly - its not un-comman

 

These will help , take your time to study them before changing anything (good tip!) take a pic of your set up and ill have a look for you.

 

 

The best way to check for leeks is to listen - a wet finger - or just replace the hose (better option) pipes often harden and go frail from high temps and years of use
