Last minute decided to make a trip to the track. been a while since she's come out to play. had issues all night getting off the line still!! falling on its face on launch. way rich off the 2 step. need to find a way to turn meth injection off while on 2 step. longer I hold the 2 step, the worse it gets. I turned the meth start # up a little and did help. running mid 11's last year so disappointed to not even be in the 11's. i'll get it figured out before next trip out. here's a couple in cab views.

What did it run? Looks real close to my passes. No juice off the line and then it boogies.

Put the meth on a 5 pin relay, and when the 2 step is active have it turn on the relay (and power or ground to turn on the meth is on pin 87a of the relay)

how is the 2 step setup? like MSD box or something in factory ecu?

run the msd box. brake pedal activated and also have a toggle to completely deactivate it. relay is probably best option. no more trips to track til its fixed. truck has so much left in it, if I can just work few bugs out.

Thats interesting...I let my meth spray on the 2step and its never a problem and I use 2 14gph nozzles. Have you tested the pump voltage before?

I use a 12 and 14gph nozzles. never tested pump voltage. its devils own pump turned all the way up. believe its around 250psi. snow controller start at 10# and full on at 14#. on one of the other runs had 2 step at 3200 and held it for a few seconds to build boost, left on 12# and it was so rich it spit and sputtered til 60'. these 2.** 60' times are getting a little frustrating.

Im not sure how that controller works, but here is a pretty detailed write up with my dealings with my alky control kit https://www.performancetrucks.net/fo...w-test-525874/
