Abs unplugged causing throttle cut?

[Kenrevo]

I haven't driven my s4 in a while and decide to take her out today and let her warm up. I noticed when I got to ~20 psi the car started to jerk, like I was going on and off the throttle, like ESP but I have the abs module unplugged. No check engine light or anything. I was thinking it might be a boost leak but I not sure since I'm still boosting very close to full boost psi. I want to log but don't have time right now. Would having the abs module unplugged do this or should I do a pressure test and look into other things?

Sure it wasn't just throttle cut?

I didn't have any problems except abs not working before I stop using the car. So I would be surprised since I didn't change anything, except for the module being unplugged for trying to diagnosis the issue.
