Great launch!
I had a similar, let's call it, "anomaly" on my 1-2 shift. What you are calling wheel hop is actually your transmission saying "I am making too much pressure, I am going to hold the shift, try for .01 seconds, hold, then try again until 2nd gear grabs at a pressure I like".
How do I know? It happened to me. For months LME and I chased this phantom shaking/jumping/pulsing coming from the drive train on the 1-2 shift.
There's a really easy fix that we found.
I want to ask you to try something for me. Ask Torrie to change ONLY the 1-2 shift to stock pressure. Leave the rest alone. Thats what LME and I decided to try and it worked 100%. I am curious to see if this works for your car too.
