Self-promotion developed fully, with energy rising (3,4)

Ross

I believe the answer is:

ego trip

I'm a little stuck... Click here to teach me more about this clue!

'self-promotion' is the definition.
(an ego trip is something for one's own benefit)

'developed fully with energy rising' is the wordplay.
I cannot really see how this works, but
'developed' could be 'got' ('get' can be a synonym of 'develop') and 'got' is located in the answer.
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is present in the answer.
The remaining letters 'rip' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
