Car hasn't had any major service besides what I've done to it over the 80k miles on the car.
Two people have suggested a slipping clutch however, it doesn't appear too slip.
What do you think it is/could be?
Not enough air/fuel or spark getting to the Engine under a heavy load? (1/2/3 gears as those are the only gears it happens in)
I do a 2nd and 3rd gear pull in this video.

It's will also vibrate going into a sharp turn.
Which makes me think it's related to the alignment/front passenger wheel as the vibrations come from that area only.

Front axle CV joint?

What specifically vibrates? The steering wheel or are the vibrations going into your seat? And is this only when you're turning, or also when you drive straight?
