Thanks.
I wasn't crazy about the 6.7 til I bought this. Been driving the wheels off of it. Has 1300 miles already. Average 18-22 mpg. 18 towing, 22 empty. Not crazy about the def an EGR but it will get deleted at the first sign of trouble. Going from 400 lb ft of torque to 800 lb. ft. of torque is great.
