As the title says when I change up gears it revs up I have no idea how to fix this any ideas

 

Clutch was changed last year car has bov adjustable actuator 3insh exhaust system and been maped

 

My hawk STI did this and it was the BOV causing the issue.....put the OE recirculation valve back on and try it.

 

May need a tweek on the map unless bov was put on after the map as said above

& Without sounding daft pal just check your oil and water along with boost pipes aswell

 

Another thing to check would be the cable and the ICV,give it a clean and squirt some lube down the cable.
Next thing would be TPS you can check voltage when open and closed to see if it's within it perameters.

 

IACV as said, not sure why a TPS would cause the revs to hang ?

 

Just something I checked and adjusted when I had a similar problem,mine also came on throttle when coasting in gear with my foot off the accelerator,I could see the TP moving when I looked at the live mapping screen and data logs.
Voltage was slightly out of perameters so ajusted that,also lubed the cable and cleaned ICV so could have been any of those things.

 

Thanks for the info will have a look
