Loosing 1.5kg from a bike won't make you much faster on a normal ride, it's all in the mind.
This maybe true...
BUT, I was 1 min and 5s quicker round our club run circuit after the changes than the previous week...
Tyre rolling resistance and improved aerodynamic wheel set-up?
I'd certainly not done any mega training between the 2 sessions.
The bike feels much more sprightly and 'seems' to respond better to rider input... maybe that alone makes one go faster?
