The on / off hobbs switch for meth is still there on the AA stage 2 kits for other reasons, say you went on a track and they didn't allow meth.

You would have to dump in some higher octane to not detonate and over heat with-out the meth.

Plain and simple, do not take a stage 2 AA kit to max boost with-out meth on or if it's off have high grade fuel.

I may have missed something as well for I'm not a pro or installer, just my 2 cents. Maybe all tracks allow meth, not sure

Note this is for the AA Stage 2 for the M3 S54 engine if wondering
Know it all .... Just Kidding but he is correct

That will suffice if you are using 94 Octane on a Stage 2 Methanol Injection is Required
