2008 Mustang GT - O2 question

[crono2120]

2008 Ford Mustang GT Manual

So, if the user option to disable rear O2's has been removed from Predator tuner's, this means the tune has to be scripted by Diablo?

Lets say I get a custom tune from Diablo that disables rear O2's. Can the tune itself be adjusted via handheld (such as timing) and still keep the O2's killed? Or do i have to come to Diablo for every nit-picking thing I want to adjust, just to keep the rear O2's quiet? Say I'm at the track and I feel like adjusting my WOT settings, am I going to keep the O2 disable or does it revert to a totally new user customized tune?

Such a headache for some O/R pipes. As if anyone cared to look underneath a car these days, except CA.

Thanks in advance.

Custom tunes from a CMR dealer can be modified just like your canned tunes...

Thanks
