I have no real idea of how the HKS VPC works (in terms of the ECU and the old sensor)but 4g63 guys use them to replace their MAF's with a MAP. So could we use it to replace our MAP with another MAP (which I would assume is better) and somehow make our ECU read the boost and have control similar to the S-AFC. Just a thought that someone who knows more then me can run with, or shoot down just as fast as I wrote it :)
