I have two wideband sensors. One wired directly to the haltech ecu and another independent AEM wideband gauge. Both showing same readings.

How did you measure the power change with different AFR?

I do not have a dyno neither have the money to tune it on a dyno for every upgrade I made to the setup. I tune on the mainly on street and adjust for the grip on track.

I measure power by time vs speed on 4th gear.

Full throttle from 2Krpm and check how much time it got to same rev limiter or 140km.

Also power and torque is easily felt on a small car like a yaris
