| Thats a pretty good start! Exhaust,chip,and cold air intake. Not sure what else? I just bought my truck 2 weeks ago with a 6" Fabtech lift, 35" tires and 18" wheels and get about 15 on the highway and 12.5 to 13 in town.How do you post pictures up? | |

| Exhaust and a good programmer will get u a 1-2 mpgs, but an intake isan't really going to help.

| There is a K&N filter in it now. What other intake system would you recommend? Thanks | |

| Do you have the K&N OEM drop in or a K&N CAI. If it's just the drop in go get the AC Delco to put back in there. If you have a CAI i would get a AFE dry filter.

| welcome to the DF...X3 on doing a chip,exhaust and intake..like it was stated above it would be far better to get rid of the K&N and go with a filter that keeps dirt out of your turbo housing..
