I'm trying to get an idea of what you guys have your start/full spray psi set at on your kits. Reason I ask is because AEM recommends setting the start to approx 25% of your maximum boost and setting the full spray to maximum boost. I'm spiking to a max of 29psi which would make my start at 7.5psi, but according to the meth gurus spraying meth too early can cause knock so I've set mine to 10psi. Its the full spray that I need to know about. If I set my full spray to 29psi (which is the max i'm running) then my meth will only be at full spray for that short period of peak load because the stock turbo can't support more than approx 22psi up top so now i'm progressively working backward. So I set my full spray to 21psi to keep it going up top.
The problem now is I have an overly rich spot in my logs, which I would assume its from when the meth goes from start to full in such a quick instance. My fuel tables look nice and smooth, but now I have to make a pretty big transition to try and lean out that spot (right around 4000rpm 310 load)
What do you guys have your settings at and do you notice this also?
