If you are going to the track get it filled so you have a full bottle. When you have a heater and cant get the bottle pressure up to 800 its empty no need for a scale I have never needed one and been just fine as soon as I felt it getting weak I turned it off that simple.

I pulled over, removed the airfilter, and the MAF screen was FROZEN. I changed the nozzle placement and got the "right" jets in it.
I usually fill it before going to the track, and empty it on the street on the way home....lol
