The SCT PRP is still the most powerful tuning software on the market for Fords. There are a couple things you need to think about when you do purchase this software package though. There are several other companies that offer tuning software for much less than you will pay for the SCT stuff. This falls into the "you get what you paid for" category. The chip version is almost $1000 since you have to purchase a chip burner. If you have an SCT chip already than it's slightly less. Where as a handheld tuner version is $750. If you have an SCT device already than it's $350. Here's a little info

Then you need to learn how to use the software. There's a big misconception that a lot of people have with these packages. The misconception is that people think that once they purchase the package from a dealer that the dealer is responsible for teaching you how to tune. That isn't how it is. The packages are do it yourself. There's hand books and CDs you can purchase in order to learn the software. You do need a basic understanding of how an engine/transmission works. If you can tune a carbureted engine then you will most likely be able to tune an EFI engine. Also, there is a PRP forum for assistance besides SCT's tech line. Dealers more often that not will point you in the right direction but like I said they are not going to hold your hand or go over you data logs or correct your program. If you need a value file for a MAF or injector size they can provide this. The software also has helpful hints for most parameters that will give you pointers. When you receive the package you must mail or fax in the signed contract/agreement to SCT, not your dealer. Once they get it they will activate your account. This will allow you to download, activate and update your software. With the download you will be provided all the value files needed to get you started on your programming. For instance if you have a blown 02 GT with 42 lb injectors and a 90mm LMAF, you will receive all the files needed for a blown 02 4.6 which will include several injector and MAF sizes for you EEC code only. These are called value files and they are used to get you started. You then apply these files to the base file as needed. This will give you a good starting point but its not a completed tune until you make the needed fine adjustments.
Another misconception is that people think that the dealer is supposed to supply them with a custom built program to accompany the package, this isn't so. Some dealers will put together a program for you like the one I just mentioned above using the basic SCT value files. They do this to help you get started. But if you are asking them to provide you with their custom programming that's another story and they won't do it. Or say you have a 96 GT and you just installed an 04 Cobra motor, the dealer isn't going to give you one of his custom programs for this setup.
The last thing is each PRP is locked to a single EEC code. You get a single chip. This is a single vehicle package. The XCal device you have is also locked to your VIN. So you basically can only tune one vehicle. If you want to add a vehicle to your package you have to pay for an additional license. Let me know if you have any other questions.
