Speed limiter @110 WTF???

I'm pretty sure ZZP tunes the Series III motors. There's a 2004+ drop down option on their PCM page.

(which confuses our Impala/ Monte owners all the time since they used the Series II from 00-05)

May I suggest an Overkill PCM. He can fix you up. If I were to buy another mail order PCM it would be from Will. He is the only one that builds a totally custom PCM based on your mod list.

And I will be going to him once I have more mods.
