I had borrowed a friends Mopar Performance PCM for a 5.9 but it pinged real bad. There's a guy over on Turbo-Mopar.com that cracks the code on the chips in the computer so you can tune the factory PCM. I do that on my '88 Caravan. He tried to do it for the 5.2/5.9 SBEC II but he said the code is more complex than the earlier computers. He said he'll get it eventually but it's going to take some time.
