You should do under 10 sec with a chip easy, without a 4x4 launch.
The AFE 1 doesn't flow very good so upgrade that to a #2 or better yet a Donaldson filter.
Check your turbo wheel...every other fin should be shorter and the edges un damanged if not get a WW
Tony's chip will wake up that engine and should give you 2mpg.
I'd get some gauges before any other mod.
