Performance issue, pre boost

[UtahSleeper]

What could cause a motor to feel like its hitting fuel cut pre boost? When I get into boost its fine, but there is no power when trying to get there and as I open the throttle, it jerks my around almost as if I was hitting fuel cut.

If more info is needed, let me know. Just trying to get ideas for what to poke at. Plan on building a boost leak tester soon just to rule out air issues.

You could just take it to a shop with a smoke tester, best $30 you will ever spend.
It is a strange problem to have issues pre-boost but be ok in boost....have you checked your ignition components ?

over fueling perhaps?

Except this car is not registered/legal lol. So it wont be going to a shop anytime soon. Plus, a tester is good considering I will probably be doing this task on multiple vehicles in the coming years.

I did check plugs and wires visually. All seemed fine. Havent went deeper.

Overfueling..........no clue. Exhaust smells reasonable, so even if it is, I doubt it is that much. Still another option to check.

Background:
I bought this car non running and most things around the motor dismantled. I have put everything back to the best of my ability, but as I go through this car I am finding that there were things left installed that may have been tinkered with before me. So my knowledge of this car is as follows.

Bought 2 owners ago from someone in Idaho. Had a engine rebuild, but 2 owners ago thought it might have been poorly done.
1 owner ago dismantled alot under the hood. Had injectors cleaned. Never reassembled or said reason for dismantling, but did say head bolts werent tight and some other mechanical things I dont recall.
Me, I have reassembled and got her running with fresh gas. Checked everything visually during assembly, but no indepth checks.

Also, it revs fine. Just when trying to move it struggles.
