stutter after chip install

I just did a 4"turbo back and a tw 6pos chip on my 96 and when i step in the throttle it seems to stutter unless you ease into it. Kind of like it is running out of fuel. I assume it could possibly be the clutch which is a newer single mass luk but it never gives off the burning clutch smell. Has anyone felt what im talking about and what resolved it?

Did you make sure the contacts were clean enough before you plugged in the chip? Does it do it on all settings?

Yes i cleaned the contacts very well. It does it on street and extreme the most. once the turbo is spooled it seems like the power is there and smooths out.

sounds like lack of fuel.

Check your fuel filters, lift pump, if not it could be too much demand for a stock and worn HPOP

Im leaning towards lack of fuel as well. I need to find a local KY stroker with a pressure gauge and it could possibly be as simple as shimming the fpr, but i dont want to try it and blow the orings off my 201000 mile injectors.
