S2 Exige 260 Hesitation Issue

Just a bit of a sanity check really, my RGB seems to have a hesitation at 2-2.5k rpm when on light throttle (3rd and 4th gear mostly) lifting off and re-applying throttle.
It’s a very noticeable stutter.

Anyone had anything similar? Throttle just doesn’t feel right on light or part load, like the TPS needs resetting or calibrating (is this even possible on a Toyota?). Had similar on my S1 Honda.

Any thoughts appreciated

changed anything on the car ?

Other than a recent gearbox upgrade, nothing

Check they have not dislodged an air pipe off the airbox.
