Guys it sounds to me like the OP is towing well in excess of 10,000 lbs several times a week. I personally don't know why he would be considering 190's with any nozzle for a truck that does this. I know he wants a truck that plays too, but I think that's demanding a lot. It's doable, but not as easy as slapping on a powermax and having a tune emailed to you.
OP, if you HAVE to have 190's go with the smaller nozzle. If it was me I'd stay down around 155's, maybe stretch it to 175's with a small nozzle. IMHO no need for more than that with a small single VGT towing as much as you do. I would also recommend live tuning.
