Hi, is it possible that fitting a new Edge performance header kit that I can drop 5PSI ? the car was running 15 psi previously.
MY93 Classic TDo5 turbo Hks blow off and apexi induction ect.
Is this possible or am I missing a pipe some where?
car seems to be running fine ,if not a bit slower.
cheers

 

Could be a leak somewhere, or the internal diameter is larger reducing the gas flow speed hence slower turbo.

 

dont think its a leak as car is running fine no lumps or hunting.I am getting 11psi exactly can anyone gimme any tests or boost restrictions I should be looking for?
cheers

 

the internal diameter is larger reducing the gas flow speed..
