Injecting prior to turbo comp' impellers

[SaabTuner]

I think a potentially easier idea (for a mass produced unit) would be two PTC resistors (change resistance based on temp, artificially heated, used in GM MAF sensors) ...

Put on a few inches before the WI, and one a few inches after ... when the resistance values are equal a light could come on, and the ECU could be informed that no WI was taking so that it would use a more conservative map.
