Stock PCM limits
What are the LS1 "01" PCM's rwhp/rwtq tunable levels.Why does 650 HPseem to be the limit? Some cars with biger motors and more radical cams make less peak HP than a smaller ect?? I am having my car dyno tuned and should be hitting these limits. Are there any oiptions besides a stand alone PCM?

The problem with putting in 640 or higher is the value will wrap around actually giving you a lower torque value. Here's a direct quote from Ken Kelly of LS1edit:
"The PCM treats torque as a signed number. Numbers over 639 set the most
significant bit. When the actual stored value gets the most significant
bit set, it is treated as a negative value.
