Heuristic parameters tuning determine the initial solutions we use during the search. This still needs to be refined for VRPTW. It also requires updates for CVRP as a few things changed since the last release:
computing times have been significantly reduced (#146, #147) so we might want to adjust the quality/computing time trade-off scale provided by -x
a new local search operator (slightly) changed the search paths (#164)
we now have a way to know if the fleet is homogeneous or not (#151) and I think it would definitely make sense to have dedicated tunings for both situations.
