any advice would be appreciated...
ive been having an issue with my revo stage 2+ golf gti Mk5...
at motorway cruising speed engine revs will suddenly drop from 3000 to 1000 and then back to 3000 suddenly. no warning lights.
it has also happened a few times on acceleration through gears, mainly 2nd and 3rd.
ive run a vcds log

Has anyone come across this before? Or any thoughts as to what could be the problem? Im running an APR fuel pump and cam follower is fine.
I had a head gasket change about 3 months ago.
