threw a code today that I've never seen before , rail pressure to high, i cleared it out and drove the trick for another 1/2 hour and it was fine , anyone else ever seen this code ?

well i tried to download a smarty over the weekend and it kept coming up error, unknown software , come to find the ecm has a file that is corrupt , i am hoping a reflash at the dealer will cure it ,
i bought the truck used with 1700 miles on it , never put a plug in tuner on it , just a tst box , i did have it reflashed about a year ago for the door alarm thing when in gear, i hope tonight they have time to squeeze me in and then i can try to download the smarty again ,
