Revs at gear change

[flash]

My K12 1.2s revs at 1200 to 1400 when I am changing gears, if I am in first gear with my foot off the gas I travel along at a fast pace:wow: When I stop after a second or two the revs drop to 750 . The Nissan garage said the K12 has a booster fitted to the rev adjuster to give smooth gear change and keep the revs high but I would prefer if the revs dropped to 750 when I pressed the clutch.Does anyone know If I can adjust anything.

sounds like an anti-stall like my dads sierra tbh i dunno if you can adjust this as it may be a ecu thing
