Since no one is helping me in the 2nd gen forum i guess ill ask here.
I have sort of a strange boost patter, i dont know for sure if its normal or not thats what i want to find out from you guys.
Basically if i start from a stop and redline my gears up untill 3rd gear i only get a limited amount of boost.
In 1st i get 2psi at redline
2nd 5psi@redline
3rd 6psi@redline
If i start from a roll at 30mph and floor it in 3rd i can get 10psi. Is this normal for a turbo? Did i port it too much? With a boost controller can this problem be fixed?
My goal is to be able to controll my boost completly, and put it at whatever psi i want. Thanks guys hopefully someone can shed some light

 

haha bump

 

Sounds like a leak. Perhaps your wastegate is stuck open a little. Your turbo has an internal wastegate?

 

yeah its an s5, check sig. I tried this a few times and got the exact same boost every time. So it could be leaking from the wastegate then?

 

I would think so. There aren't too many conditions that will cause what you are describing, at least none that I know of (maybe a MAJOR intake piping leak?).

I'm not too familiar with FC terminolgy (S5), that's why I wanted to make sure about the internal wastegate.

 

ok well i do have a major idle issue right now, my car idles at 2k all the time. Also the old *** tube comming off the turbo has a huge crack in it so maybe a vac leak has somthing to do with this...
