That wasn't really where I was coming from. A couple of points:

1) By 'yellow injectors' I assume you mean std cossie? Well they're low-impedence and will eat your ECU alive.
2) The fuelling would be completely wrong, and the chip may not be calibrated at the higher boost levels you want to run, so who knows what'd happen.
3) Chip may have a boost cut in it anyway to stop you going any higher.
