    It will... You already have the LS1B PCM, swap engines and full flash a fullsize OS (I think there's a certain one floating around that has 4LO intact). Done.

    Transfer case setting, scottcmb. I usually race in 4HI. In 4LO you can almost do a mini wheelie in some trucks. Neither is good for driveline wear.... oh well
