I experienced some shuddering under WOT and putting a new adjustable fuel pressure regulator cleared it up. I think the cause was bigger injectors, a hot wire kit, and a new chip. I'm assuming the stock regulator couldn't keep up. I'm pretty new to these cars and by no means is this your issue but thought I would share what i experienced.

I have not got the chance to do anything yet working 7 days a week currently. This question is more for all turbo Buick owners and my own curiosity.
