Saturated Injectors (NA high impedence) can be used in Peak Hold (TT) systems, but not the other way around. So if you want to use the better (larger) injector you must do this conversion.

Quick question regarding Peak/Hold
Are you 100% sure TT uses Peak / Hold drive for the injectors. I always thought the injectors were low impedance injectors with a series resistor but driven in saturation mode - not peak/hold where the ECU modulates the current.
I'll toss a scope on one of my injectors to confirm. If the ECU pulls the injector to ground for the entire duration of the injector period, it is being driven in saturaion mode not peak/hold.
