bingo. if he's in a good mood, he won't charge you for it :hihi: J/k Lex is the man, he'll hook you up. the 411 beats the crap outta the old blackbox PCMs

yes lextech is the man
you will not be disapointed with the 411 computer
do a search on here or on thirdgen. org there is some codes you have to turn off along with vats:grin:
