Most people with tCs use piggyback engine managment to tune fuel when they go forced induction. Naturally Aspirated, tCs don't make much power with a piggyback or any other NA mods. Therefore, power wise forced induction is the only cost effective way to make power on these engines. However, I wonder if a piggyback could help mileage wise?

Our ECUs are not too piggyback friendly either, the ECU likes to "fight" it. The best solution is standalone engine management, and that is big $$$.
Oh well, that's a shame. I think there was this "sweet spot" in early OBD I/II controllers where the ECU was "dumb enough" to fool.

I like to ask this because there was this dude with a first gen Mitsubishi Eclipse with an Apex'i type of fuel controller. He could go to the track on the weekends and race, but manage 40+ MPG on his weekly commute. Best of both worlds, thanks in part to his low-IQ ECU.
