I have a meth kit in my car but spraying before the supercharger. It does not have a big effect since the afr did not change a whole lot on the dyno while tuning it. Right now I turned the meth off all together since its wasting meth. I plan to tap the nozzle after the supercharger into the lower intake to get a better effect from it. If not then I am going to get rid of the kit all together and convert over to e85.
