Just got a reman PCM flashed with my 05 5.7 SLT info, got it installed and ran for a while but check engine light never went off and alternator is not charging battery where is should be which gauge shows and I confirmed with DVM. Output is only 11.5V and I also got more codes thrown that I have never seen. P0335, P0443, P0498,P0622, and P0403. I wonder if these are just because of the rough startup while PCM recorded info initially because the truck runs ok except for the low alternator output. Does the alternator output go through the PCM or controlled by it? I don't know if I should get a new alternator or request another PCM. Alternator was fine before. Problems I was having were tranny codes which I got fixed and codes would come back, truck rpm would jump up for a split second, radiator gauge would say truck is overheating when it wasn't and some other quirky stuff.
