Hey Guys.
Just having a few issues with my c34 Stagea
firstly the car is running standard everything, apart form ebay dump, and full 3inch.
never had this problem untill a week ago, where as the car is only hitting about 4-5psi of boost no matter what gear you are in.
and also i have a Greddy informer plugged in, and once i am going full throttle foot to the floor it is only reading a maximum of 83% throttle through the informer gauge.
any help would be appreciated, i have also checked all intercooler piping for boost leak. and no leaks seem present.
help will greatly be appreciated.
