Well its not really a stock car anymore if you have a VF22 in it. I'm trying to decipher what you are asking...
The previous owner probably had the car protuned or tuned with some sort of Engine Management in order to run the VF22 properly. I'm assuming the tuned map is still loaded on the ECU? Even if it isnt, I'd look into getting a custom tune, to support that turbo and get the full potential from what it has to offer. You could even look into putting a bigger intercooler in, along with a new turbo inlet pipe. That's my suggestion.
I think this is the answer you were looking for, but I'm not 100% on that.
