Throttle Body Overbore - TPS
I have been looking into this and a few questions came up that I searched for but couldnt find the answers to.
What adjustments, if any, would need to be made to the Throttle Position Sensor?
Will the ECU need to be adjusted as well?
There just isnt much info on yotatech about this.

no adjustments to the TPS the butterfly moves just as much/little as before it was bored
the ECU doesnt care, all the air has to pass over the flapper way down stream. Your just creating an easyer path for the air to flow into the intake plentum. (but still have to go through like a 3 sqin area were the AFS is.
