Hi all I have just brought another scoob, this one is a v limited jdm n reg.
It has a full decat air filter and now a td05. Since td05 going on its seems to over boost!
My gauge goes to around 1.4 and engine hesitate. Should this be doin this?? What should I do?

 

Take it to your nearest Impreza specialist.
What turbo did it have on it before as the Td05 is a standard turbo for that year car.
I would suggest it may be a wastegate problem.

 

if it didnt have the td05 before and does now then needs mapping

 

It had td04
