I honestly hope you are joking about being a test pilot.
The lift is the same, ie equal to weight however you get it in un-accelerated flight at any speed. (except that due to downforce being greater on the tail, slightly more lift is required from the wing is required fully configured unless you can shift the CofG)
The difference is how much air the lift is being generated from/acted upon.
Lots of air a tiny bit at high speed, or not much air a lot at low speed.
