You can still run methanol on a Cobb tune but you need to have all your ducks in order with a proper fail safe and 3rd party controls. Naturally, on stage 1 its quite useless as the benefit of methanol is only found when turning up the boost and adding ignition.

There's zero proof that any of the so-called "failsafes" actually save the engine from failure...they're just there to lower boost and/or introduce some timing retard in case of meth flow failure but this has never really made running meth on high boost any safer...on the other hand, having it doesn't hurt but i really think it leans more towards a false sense of true "safety" that towards true engine safety...
Its great that it allows a tune to run lower boost when there's no meth flow BUT if that meth is being used for octane enhancement (as its the case in many setups here especially on questionable pump 91 gas) and meth flow stops at high boost high RPMs, there is no proof today that any so called failsafe "prevents" sudden motor failure
