    I forgot to mention that I have:
    cold air intake
    true dual exhaust w/ cats only
    oversized tires, i think someone said you can have that set up
    looking to get poweraid TBS
    and possibly dual electic fans in the future

    I want more power, obviously, but I want it to improve my MPG too.

    Thanks,
    Dan

    Nope. I believe they are in southern cali.

    Justin is a professor at EFI Live.

    Seriously, there is nobody better qualified to tune your 98 and up GM pickup.

    He will send you a datalogger to gather some info and a spare ECM so you can run while everything is in transit.

    I don't mean to dog the other tuners. They are reputable as well, but Justin is the best. Why go with anything less?

    BTW, if you are in the Dallas area, would you be willing to do some welding work for me? Not having a welder is a serious pain in the ass. I need two cats and a custom battery tray welded together.

    I don't have a welder. Sorry. Wish I did though.

    ALL? More than you can imagine.... :) "You can't handle..." never mind...

    VERY Simply put, timing, fuel, trans shifting and at every possible rpm and throttle and speed range and condition.... It honestly isn't anyway to list it all and make sense of it unless you have spent a lot of time in it.
