Obviously the Corvette is engineered. Best of what's possible in the Bubble except for the Thrusters which aren't quite maxed out. That's basically the norm nowadays after they have gone on a massive crusade to make engineering easier to do, it's not like trying to get a full set of god-rolled modules used to be. However, it's probably not even at the peak of its potential power yet, as I still need to do some tech broker stuff and powerplay to experiment with; I've not visited the Colonia engineers yet for further optimisations; I also don't use premium synthesis to boost my damage output either and my SLF pilot is not fully leveled yet. There's potential for even more performance out of my ship (to say nothing of me improving as a player).
Complaining about difficulty on the hardest difficulty in the game seems a bit counterproductive too. Attempting an Elite ranked mission is attempting the Impossible, the Ultra-Nightmare, the LASO, the Master Ninja, whatever you want to call it. Elite-ranked stuff is not meant for the "average" player by any sense of the imagination, average players would be much better suited for missions around the competent / dealer / surveyor ranks; y'know - the "average" ranks. High ranked missions should be something to aspire to in the long term, not a given once you have put a weekend into the game. The highest difficulties should be pitched to the top players, the middle difficulties should be pitched to the average ones and the lower difficulties to the beginners; not pitching the highest difficulties to the average player. The only time to complain about the highest difficulties being too hard is if they are hard to the point where literally nobody can legitimately complete them.
