I have my meth kit kick in at 3psi so it doesn't go to waste.

 

Mine kicks in around 4psi.. I get pretty good meth mileage

 

I put the snow performance 2 gallon under my hood

 

Back when I had my supercharger and used water/meth, I used a spare coolant reservoir. It looked decent, fit pretty good, but best of all the low coolant switch could be used as a failsafe when I ran out of water/meth.

 

About 3000 miles a year, so not much but still. I have it turn on about 4 psi and was full in at about 20psi with 2 14gph nozzles.

 

i dont plan own using it a lot .that why i bought hpt tuner .long trips or just crusing not going to run my meth tune up. mainly using it at the track.truck is strong with out it . just want more power at track.when leave track switching back to my regular tune
