    Fuel pump, 42# injectors and a good tune worked for me.

    This worked for me too. BUT, if you plan on running more boost in the future, plan accordingly. I'm having to buy crap over again, as if going FI isn't expensive enough.

    How did you like installing it? How long did it take you?

    Lightbulb The fuel answer

    Been there done that:

    1) upgrade the Injectors, 42# or better
    2) upgrade everything behind them
    a) The Pump, racetronix works great, easy to install, great wiring too
    b) The fuel lines, NO (no worries unless you plan on exceeding 800+ hp) the RAILS, NO, again not required unless you really push it up there
    c) Fuel Filter (stock is ok, aftermaker has better flowing products)
    d) upgrade your plugs to a colder range by 1 step min.
    e) while your there do the wires too (talyor, msd etc, is a good choice)
    f) TUNE IT - TUNE IT - TUNE IT all the above is worthless without it
    g) Stop buying the cheap gas (OUCH TO THE WALLET!)

    Here ends the lesson of the day.

    I forgot about my fuel pump too. I also have a racetronix fuel pump. You cannot go with a fuel pump from STS because they do not have the correct one for an 02. (trust me, spent lots of time dealing with them over the fuel pump). I'm running an aftermarket fuel filter (it was time to change it anyway) and I upgraded my plugs to RKG T6 iridiums with a .28 gap. Runs like a dream!

    WHERE DID YOU GET THE RACETRONIXS FUEL PUMP?
