hello
I want to add 2 cents worth. Tbms sends a bunch of pcm's to roush with this spec , our application for use ford 2.3l 4x4 w/automatic transmission, so rousch looks up tune info for ford truck, they have worked with this vehicle before. they tune the engine for a 4x4 truck with some up grades for more hp. now all stallions have the same tune up which is shown in dyno first run, dyno operator buys license to up grade ford products, some have internet access up dates according to vin number. ok flash system remove all data or only some, set data into pcm, start and run vehicle set up what you want for specs(dyno run)
at this point you can play with tune, I have it just right now. flash system store data in pcm. now that you have license you can always tweak it later. if need be, second run dyno shows good results. as for the product Richard showed, these products return the original tune up specs as was flashed into memory to begin with. they help repair system but will not change tune up. probably did not explain this very well either.
