Thanks for the legal heads up Boxhead. I won't be locking any tunes in future, and to be honest I have often wondered how long it would take before this came up.

I think I'll just do unlocked basic tunes for the masses and keep all the trick stuff for friends...

Rebel1, I think you are totally correct. I have HPTuners and as you rightly pointed out, I just modify bunches of "GM tables" to achieve my desired result.
The one person that this thread started about though, does write his own code.
