Are you having to add meth to your reservoir at a rate equal to what you should be spraying?

I've only had the 3rd nozzle hooked up for the dyno and the 1 run at the track. The climbing IAT issue was there before too

I went through a liter or so of meth on the dyno, the one run at the track was to short to measure how much was really used but the level is lower.

I guess I'll have to tear it all apart and start over checking everything... I think the consensus here is my IAT shouldn't be that high that fast with what I have.

Last year I logged about 135-140 lbs of pressure (didn't have the M3 nozzle installed) and my IAT went from 82 to 158 with about 12.6 voltage. That was with an old IAT sensor

Wish I had a flow meter installed too....

Place a 10ga fuse link on the back of the alternator and solder/heatshrink it to a 10ga wire and run it close to your power feed on your meth kit. Then pick up a good 30/40a relay and use your fusebox power to switch power off that 10ga wire to your meth system. Solder everything you can. Then go to the kick panel or tunnel and sand it down to shiny metal for your ground. Start the car and test your meth kit with the car running. Your pressure should jump significantly with these updates. Let me know what it does.
