I'm looking at running meth with mine come summertime. I don't really like the idea of the TB spacer to run it, but dont seem to be any other options (I don't want to inject pre TB either, since i'm going to be using it for fueling).
I know it ends up being more expensive than AUX in the long run but its just not something I want to do for every day driving. I'm super happy with the power it puts down right now, but being able to have an extra 30-40whp when I want it is enticing.
