Where can I find info on a custom FMS chip?

Once you mess w/ the intake/fuel/exhaust, many times a dyno tuned chip is all you need to make your car purr again. I was thinking that you have alot more air flowing now, w/ almost stock fuel delivery......you may need to raise your fuel pressure. What's it set at now? Is the MAF set up for the 24 lb injectors?
