Hey All, 

 

Another boost issue for you!

The other day i was playing with my boost controller and 1st and 2nd gear were boosting really well but i was getting fuel cut on 3rd and 4th gear. 

I read online that this was caused by the Turbo VSV and that the easiest way to fix it was to disconnect the hose and then plug both ends (the one on the wastegate and the metal tube on the other end). 

So i did that (i just removed one end of the hose that was there, clogged it with a screw and clamp, and then put on another bit of hose to the other side which is also clogged) and it doesnt have any leaks. 

 

So i tested the car around the block a couple times boosting in 2nd and 3rd gear and i cant seem to get over 7psi

I know that the boost controller as working as before the VSV line was clogged it was running 12psi in 2nd gear. 

 

Any ideas?

 

Thanks in advance!

Is the boost controller still connected to the turbo compressor housing?

Sounds like your running factory wastegate pressure which could be caused by an incorrectly installed boost controller or just setup incorrectly
