Simota CF650-6 Air Intake Review

[NYC-SE]

This still doesn't make sense to me. For one thing the Yaris auto has a lock up torque converter, so there should be no affect from that. Essentially there is a direct connection between engine, trans, and wheels when torque converter is locked up. (I may be wrong but I seem to remember reading somewhere that it locks up at 5MPH.?) No gear ratios have been changed, I don't see how engine can be turning at a lower RPM while wheels are turning at a constant MPH.
