UPDATE, I've got around 1,200 miles on the truck since the install, no major issues other than my vss coming unplugged going down the road (which would not let it shift out of first after I came to a stop). I'm getting 12-14 miles to a gallon on stock 3:42 gears, I just picked up a set of tons last week I'll try to put in over the winter. Which will probably get pushed to spring because I just moved to iowa, I'm sure the wife will be driving the diesel,her car will probably sit in the shop and blaze will get to collect some of this Midwest salt! I do have a problem with my bright lights dim works just nothing on bright. I'm not sure if it has anything to do with me changing out the cluster or the hids I put in.
