I agree with Jolyon Palmer this isn't purely engine related, Max was way off Norris in sector 2 & 3 and those are not particulary power sensitive. Also Max was complaining about lack of grip front & rear.
Red Bull will have to do some quick analysis and adapt the setup as best as they can for qualifying. Even if the race pace has improved, dirty air from a Ferrari or a Mercedes will hurt him. At this stage 3rd place looks like the best outcome Red Bull can realistically hope for.
