Which AEM kit are you referring to?

I know the tuning is required for optimal usage, but it seems the BMS Stage 1 is the only thing out there as it'll also control their own meth kit. Problem is I'm flash tuned to a stage 2, so going to stage 1 would be going backwards.

At this point I'm planning on going cheap and using 30° washer fluid with a bottle of Heet and using it for it's cleaning ability and whatever adjustment the ECU makes by itself in noticing the increased octane. This is why I can't decide on a super simple $300 kit or a fancy $900 kit that I may never get full usage from.
