Hi everyone! the first thing is sorry for my english (i´m from Spain and is really complicated speak english for me.)

I have a problem with my boost, has maximum 3 psi... 4psi sometimes. The last owner made a simplification of the rat nest. Exactly the next pic:




and I felt slow the car so,

I installed a power FC with commander, and finally a boost controller (GREDDY PROFEC OLED):





This is my setup (VERSION 2):




Maybe I installed bad the solenoid?? this configuration is right? or the exiting source input is in the front port?







I´m not sure what is the problem, I checked y-pipe, and the hoses from boost to manifold (maybe not really good check... because I´m not sure how to do it).

I can hear the turbo working, and the blow off sound very strong....

So, can someone help me?? What can I try?

Thanks a lots!

 

The front port 3 is for plumbing in an external wastegate

 

Hi Chechist,
Does your max PSI stay constant throughout the whole rev range?
If so, it could be a boost leak or even a blocked CAT that is hindering flow.
Still running the stock blow off valve (BOV)? It may be leaking.
There are many things that could cause a low boost issue. Its especially harder if the rats nest has been messed with.

 

Thanks guys! Finally I find a really big crack in the intercooler pipe! But I could to see the crack with poor pressure.

I bought items and I made a handmade tester:

- Bottle of wine.
- Bottle of cappers (for cap)
- Cheapest air pump.
- Cheap Shisha



And..... TADAAAAAA!!!



and after push with my fingers:





So... 3psi for this crack not bad!
