my yaris has not seen a dyno ever since I owned it!

anyway, I think the result can be seen if one has a scangauge II / OBDII and the thing to watch is the air/fuel ratio (I may be wrong on this) .

if the ECM is fooled by thinking it is getting a cooler air, it may allow a richer air fuel mix. theoretically, a liitle more fuel will give a little more power.

our yaris have a knock sensor, I think that will prevent any predetonation in case I have too much fuel in.

now, i have two problems:
1. I do not have the A/F gauges to see the results, i may have to rely on driver's instinct on this.
2. still I do not know which wire should i insert the variable resistor.
