FN2 lifting off in low gear

[Vyse]

I am wondering if there is something wrong with my FN2 or is it normal. If I am doing around 30mph in 2nd or 3rd gear then lift off the throttle completely. The car seems to slow down a lot by itself. Seems the engine braking is quite harsh. Is this perfectly normal for the FN2 or do I have a binding brake problem?

Also, sometimes I notice the engine braking only after a fraction of a second of lifting my foot of the throttle. Is this due to the rev hang?
