Sway left to right during hard acceleration

[SC509]

Hello, new here…
I have a 2023 R that just got back from an upgrade to a Velociraptor 1000. During hard acceleration (all wheel drive T/C on) the truck pulls hard left, then right and so on. You have to be on your game to keep it in a single lane. I noticed a slight pull left/right when it was a stock R but this is quite aggressive now.

Any suggestions?

1000 ??? as 1000HP you mean ??? perhaps try to put 200hp more and it will be ok...
Seriously, I don't know,before the tune, did you have this problem ?
1000Hp, ....mmmm I don't know what will break first, truck or driver ...
I guess to keep such power on the floor you need a dragster and not long travel suspension truck...

Had the same exact problem on my 22 37pp truck. Its your wheels and tires. I did hub rings and swapped tires. Problem gone. BUT.... first I would check that you front shocks have been zero'd.
