Some possibilities:

1. measure calibration of TPS sensor, also measure ground & reference wires according to manual

2. measure MAP sensor output voltage at idle and 2500rpms, also ground and reference wires according to manual.

3. measure vacuum at MAP sensor at idle and 2500rpms. Verify 5-way T is sealed and not leaking on any hose.

4. verify exhaust servo valve operates properly. Cables are sliding easily.
