all i did to mine was dual exhaust, headers, cold air intake, power programmer, and nitrous, and i'm running the 1/4 mile in the high 14's. that doesn't sound to impressive but you have to remember that it's a full size 4X4 truck. it doesn't take much work to get these trucks running strong.

14's? WOW!
Yeah, that's smokin for one of these beasts! Well, the nitrous is where the majority of your power is coming from is it not?
how fast does it run with all those mod's W/O the nitrous?
that's awesome though!

Well I haven't added the nitrous yet but with Gibson exhaust, tuner, K&N filter, 75mm throttle body, 80mm MAF and a factory tech valve body in the tranny my 02 F-150 FX4 fully loaded has been timed at 16.81. I plan on adding the nitrous later and hope to get it to the 14's.

yeah nitrous made the big difference. stock it ran in the 17's. with all the mods and no nitrous it was running in the low 16's. with 50 shot nitrous in the high 15's, 100 shot the low 15's, and with 150 shot the high 14's. i can only get in the 14's under perfect weather conditions. it's got to be nice and cool outside.
