How do you guys like the 6.2? I'm most likely be selling my duramax in the summer and really want to get into a nnbs. Mainly been wanting to get a denali after seeing daniels build on here. Any big problems I need to be aware of beside the afm which I will turn off with a BB tune. I will most likely level, exhaust, Volant cia and 33" terra grapplers or toyo mts on stock wheels.
