So I live in Colorado and quite often I find myself driving through the mountains. On the big inclines through the passes she does great, with more than enough skinny pedal to pull what I need through the hills. However, my problem starts after I've stayed in gear with no throttle % while going down hill. The truck goes down the hill normally but, as soon as I tip back into the throttle the truck will hesitate, stumble, bang, and pop just before chugging a big cloud of white smoke and clear up. It runs normal after this and I've noticed that if I just give it a good goose right when I notice it, it will clear up quicker. Any ideas? Thoughts? Fuel system is regulated at 15psi. The only thing I don't have in the signature is the NV5600 swap, which i would not think to have any affect to my symptom. Thanks in advance.
