Mini Maxx and DPF/DOC delete installed. Defuel settings?

Got the mini maxx, AFE stage II and dpf/doc delete installed today. Man this thing is a beast! What should I have my defuel settings at? I have Pyro 1 at 1450. Boost at 45. Coolant at 210. What do you guys recommend for a safe settings? While making a few runs it defueled because of pyro was over 1450. Think it may have defueled for going over 45 psi as well. This truck rocks.

Also what are the 4 most important things to monitor? I am monitoring pyro, boost, tranny temp and oil temp.

Interested as well in the defuel question. I monitor boost, pyro1, trans, and coolant.

What is the best speed for torque converter lockup? With the 55 mph lockup speed when cruising around 55-60 it will lock and unlock. Should I lower it to 50 mph?

i did the 45mph lock up and i think it is perfect based on my driving style. im on surface streets alot were the speed limit is 50 mph so i think by doing the 45mph lock up it saves on economy.

That makes sense to me. What would be the benefit of locking up higher? Say 60-65? I see no reason why that would be good. Anyone know where they lock up when stock? I never even looked before.

I don't really want to set it back to stock and have to do the tranny re-learn if I don't have to.

I have mine set to 50, that works for me. I would not be against 45 though

My truck surged pretty bad when I set my TC lockup at 45. Casey from H&S told me to increase the lockup to 55 or 60 since I had 37" tires. I did that and the surge went away.
