Not sure if it helps really, but Renault are ruling out a major upgrade this year

It was Red Bull who said that there would be an upgrade [in Baku],” said Abiteboul. “There are upgrades permanently - every single race we are making some small improvements.
Sounds familiar !
Frankly the next big upgrade will be next year. Then we will have a completely new concept.
That is odd, I'm sure they said they had a new concept this year, with much more headroom to develop.
Anyway, Renault are struggling as well on the upgrade front, although of course what they already have is much more reliable and somewhat more powerful than Honda.
Bonus question, has any engine manufacturer ever brought an upgrade of this magnitude mid-season (let alone in the current PU era) ?
the Honda PU needs a whole new upper-end(heads,cams,injectors,pre-chamber,main-chamber,pistons) and redesign MGU-H(stress is expanding bearings casing).....also do not forget all the new mapping!
(rumour via vtec.net). It is very much needed, but a tall order.
