issues with 228/232 110+1 cam
see my sig with that cam. Stock Heads, LS6 Intake and P&P TB
The Best V8 Stories One Small Block at Time
The solution is in tweaking the timing and the IAC. The throttle cracker table and the low airflow/low rpm timing need to be adjusted for the cam to drive 'like stock' again.
THE COMMON MISCONCEPTION IS THAT IT DOESN'T HAVE ENOUGH TIMING. In truth, it has too much timing. After dialing in the AFR, I dropped my low airflow and idle timing and I have virtually no bucking anymore. I also had to zero out the throttle cracker table for the 1600 and 1000 rpm rows. By doing that, the car will decelerate and hold a constant speed from 1100rpm on up....and that's on a 232/238 112 LSA cam (tons of overlap).
Details of what I did and what some of my tables look like can be found over at EFI Live's forums in my sticky:

You have to understand that the cam is going to move your torque curve around. For example, my setup (P&P 241's and 232/238 .595/.605 112LSA) makes 330+ ft/lbs from 3100~6700rpms and peaks at only 390ft/lbs right around 5000rpms. It's not exactly the same as the cam in this thread. But, there shouldn't be too much difference. Compared to a typical bolt-ons car that makes 340ft/lbs before 4400rpms, it's not that great of a difference. However, the design of the cam is for more high-end power/torque. That's why it peaks ~50ft/lbs and 700rpms higher. So, if you're looking for kick-in-the-pants, low end, get the f*ck out of the way kind of power, you picked the wrong mod (shoulda went supercharger).
