Rpms not dropping

[gikser]

Well adaptation didnt do the trick. Curiously enough the car idles perfectly fine at a standstill so it only happens when driving mostly on the highway. Im stumped.

Bump. Anyone has any clue?

I would start with using Durametric analyzer and look at the pedal position % as you depress and release it and see what it shows. Also what the potentiometers read.
Pedal Value - 0.00%
Pedal Encoder Potentiometer 1 -Voltage
Pedal Encoder Potentiometer 2 -Voltage

If you don't have the Durametric system, find someone that does.

Being as im suspecting the throttlebody i guess its a good excuse to upgrade to the ipd plenum and bigger throttlebody as well as the softronic tune which comes with durametric
