I'd say do the rockers before the PCM. You can get a ton of power from those. They are quite affordable considering how much power you will gain from them.

Put in perspective to....you could spend maybe another 1000$ and still not be faster than that stock TransAm next to you. Definately none of that ebay piggy back stuff, it will just be a failure. But rockers are probably the best way to go.

Thanks for the good info. Would you happen to have a link for these rockers? Where can I get them?

You can get them here: http://intense-racing.com/ All sorts of good stuff for us Series 2 guys. If you do get the rockers, go 1:9 ratio, oil restricted pushrods, LS6 valve springs and retainers.
