The first thing you need to figure out is how big the injectors are. Unless you get a custom flash done, a mail-in flash will not get the scaling right without the proper injector size. The utec can scale up to 1000cc injector, which I doubt you have but just telling you for some food for thought.
GO to the Turboxs website and you can download the program for free. Put it in a laptop, get a serial cable, and you can get into the utec.
Once connected, go into user constants and look under injector scaling. THe value there should give you a ballpark figure. Bear in mind though that the value there can be smaller than the actuall injector size to help in scaling them.
The best way to determine the injector size is to send them to a company such as RC engineering and have them clean, adjust, and measure them.
