My next investment for my car is a reprogrammed PCM. 2004 Impala SS, mods are intake & catback. I will be going down to a 3.4 or 3.5" pulley soon too, just havent decided on which size. I have looked on 3800performance and zzp but unsure as to what options to select. Any help is appreciated!

There is also Overkill's PCM which I have heard great things about, both S/C'd and N/A.

I'm looking at getting one as well, but will be keeping my core PCM for troubleshooting purposes and if I sell/trade/wreck the car. heh

My tips would be to ensure you pick the right octane, and stick with it. ;)
