What mods do you have?

Could be something as simple as the wrong octane of gas. Need more info on the car.

Could be any one of these you mentions. Gotta start somewhere.

I would start by checking all your hoses under the hood ext. If it was me I would datalog part throttle and gently ramp up until the problem occurs and see if anything shows up weird in the datalog. I would be cautious, the bucking could be a temporary lean condition.

would help to know things like - did you just buy the car and it's doing this, have you owned it for a while and this is a new issue popping up, did you make any recent changes etc...
