I already installed the 93 octane tune , but forgot to turn off the first 2 tm settings.Can I just go back in and do it , or do i have to do the whole tune over again? Its in a 2004 chev avalanche 5.3 L 4x4 u7193 thanks. p.s. will this kill my tranny?

you need to hook up to your truck like you did before to install the tune... select the same tune you installed before, and then select "Modify Tune" instead of install tune... make the adjustments, then press ESC button a couple times, it will ask you "install tune now?" - answer YES to that and it will install the modified tune.
