"The real “punto debole”, or weak point of the 2014 car was of course the power unit, which was poorly conceived by the Ferrari engine men and they face a long road to catch up. The Gazzetta dello Sport’s Pino Allievi, whose finger is closer to the Maranello pulse than any other F1 journalist’s, says that
Ferrari PU has 80hp more than last year’s, due to new layout, better combustion and a more efficient MGU-H, recycling heat energy to maximise the turbo. This power gain is encouraging, but Allievi notes that
the gap was 60hp last year and Mercedes is understood to have added 50hp with its 32 tokens spent over the development phase. So that puts the Ferrari still around 0.5s to 0.7s a lap behind the Mercedes when operating at the maximum. Ferrari’s engine people implied that the lion’s share of the tokens have been used up already, so there will be some updates during the year, but not any game changers."

Well it seems they are now 30HP behind Mercedes with not much chance to improve significantly..
