The tuning is done within the pcm. Way overkill going with 38lb injectors. There is no such thing as cam break-in when you run a roller camshaft. They don't need any break-in. You can safely run the stock injectors up to around 425hp, and you won't hit that number with those parts.
Try pcmforless.com . You can send them your computer, they will reflash it (tune) and send it back to you, or you can purchase a computer directly from them. If the fans are on the entire time, it should have a check engine code being displayed.
