    You have high expectations for a stock heavy beast. You have done mods but nothing to really get any great gains out of it. 12 second 1/8 mile runs are very common of 4wd trucks if they don't have a ton of work done to them. Time to dig a lot deeper in the pocketbook to buy some forced induction.

    4wd really weighs a truck down. Your shorties, programmer, and tbs are probably making minimal gains. That leaves the cai, catback, and 4.10s, so I would expect you have dropped about .5 second off your stock time. Those times are probably about right, but once again, what motor and vehicle are you running?; stock tires?

    You've scratched the surface for performance mods... I'm right around the same level.

    bro loose the programmer, shorties, and get a tune and some long tubes. Dont feel bad though. thats about right for a 4wd reg cab. I estimate with the nelson tune and lt's you would see a 15.0 @ 88mph. 13.90's with spray.
