issues with 228/232 110+1 cam
I run a similar cam grind, 228/232 111lsa. My car bucks a little in the 1500rpm but it comes with the territory. With "basically" stock 243 castings, ls6 intake, and stock tb it made 424rwhp and 397tq. That was in 93 degree heat, 85% humidity, 2783ft DA. Its all in the tune up my man. Luckily it only took three pulls to zero mine in.

see my sig with that cam. Stock Heads, LS6 Intake and P&P TB

The problem won't be solved by a SD tune.
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).

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).

I ran a best of 13.2 at 112 last night. Friend managed a 12.9 at 115. It's really hard to launch with the MX's. It either spins em or bogs hard. I'm currently looking for a set of rear wheels for track use. If I break the rear it'll be an excuse to buy a 9", right? Car hauls when it gets moving!
