Just last night i reflashed my 02 ls8 with the xcal 2 and a 93 octane program i got from steeda. Well after about 15 minutes of driving i got CEL. I pulled the 3 codes and they came out to be p0171, p0174, and p1000. Well i cleared the codes last night and on my way to work this morning again after about 15 minutes it came back and i pulled the same codes. The car sounds great and runs really well, i can feel the difference with the tune. Any idea what may have happened and/or what those codes are saying. Thank you in advance.
