I got a couple nice logs back from the S4 owner. Blue is with WI. We can still do some tuning with the controller. Dual 5 GPH Nozzles. 22 psi.

 

New updated results from the S4. What a huge difference tuning the controller makes.
Blue is the latest results after more tuning.
Dark Purple is with a little tuning
Pink is the from the earlier posted logs. 0 tuning.
Red is no water injection

 

Still Available as well. I'd love to hear some feedback from the couple of you that picked up kits
