An ignition upgrade will benefit throttle response and will have its own associated power gains. The problem with the programmer is that it doesn't know ALL of the mods that you have and other than the questions it asks you, it assumes a stock engine. That is why an off the shelf programmer will always be second to a custom pcm tuning.
Things that really complement each other well are things that allow more cold air in and more hot air out. An intake will reduce the restriction associated with the stock intake, but that is peanuts when compared with a larger bored throttle body, higher ratio rocker arms, a larger cam, ported heads, headers, a free flowing exhaust, or any combination of the above (besides higher ratio rockers and a cam because you'd probably run into the piston with the valve = bad).
Of those, headers and higher ratio rockers are the easiest to do and would provide significant gains. I would have to do some digging to find the spring rate of the stock valve springs to be able to tell you if they'd need upgrading for the rockers and associated higher tranny shift points to take advantage of the rockers.
Here's some info on rockers and springs:

In my scouring the internet this afternoon, I found another very interesting article, but not necessarily pertinent to thread, but here it is anyhow:

That will be answered on a the right thread.

You will definitely want to change your oil after the upper intake cleaning with seafoam.

After how long? I follow all the sea foam discussions and I have yet to find a place where they say an exact period of time before the oil should be changed...
I do the seafoam, ram around in it til it stops smoking, and let it cool off for about an hour (drink some beers). Then pull/check or replace the plugs and at the same time do a complete oil change. If your plugs look good, then just check the gap and toss them back in, but there is always the chance that some loosened up carbon could get stuck on the plug and foul it out. You should check up in along the center electrode for carbon buildup or chunks stuck up in there.
If you need any more information, let me know.

Once you try it you will never go back to using your old oil.
royal purple is a great oil indeed but it will do nothing for you if your engine was broken in with and consistantly maintained with conventional oil. in my eyes unless you are running a straight weight you arent getting the lubrication that you expect. with your engine was broken in with a petrol oil, which it more than likely was, go with a grade 3 petrol oil, like rotella or delo.
