Absolutely not- the car should be very smooth.
I can almost guarantee you have a boost leak. Remove and inspect the
michellin man hose for cracks, as it is the most common culprit. If it's not
that hose, and all your clamps are tight...you will make life a thousand times
easier for yourself if you build a pressure tester and test the system:
...otherwise, there are a dozen plus places you could have a leak.
Your O2 sensor is probably fried as well(leaks cause super-rich running), and
I'd fathom a guess that your catalytic converters didn't look too happy when
they came out.
