    Twin Turbo sierra startup

    A little late on startup, but it finally happened.

    All systems checked out ok, pcm was loaded with a calibration 3bar.
    Ignition ON
    Fuel pump ON
    Push button start, fired up the first time. I just love when that happens.
    No issues!

    Now put the interior back in and finalize all the wire and clean up.

    It's a gutted '00 Sierra, slammed like a mofo (was like that), we did coil overs in the front (the rear setup was done) fab9, ladder bar setup, 5" Driveshaft Specialists equipped, TH400 tbrake, 8pt cage (might brace it some more), alum dash, all new wiring head to toe with minimal wiring, every system has a quick disconnect, pcm controlled electric waterpump, efan, switched fuel pump, boostcontroller, tbrake, 2step, LED head/tail lamps (not legal but those little things are bright, ran off one 18g wire for all lights, low voltage), new steering, removable steering wheel;
    forged sixo, 370, ls3 heads, victor topend, a/w intercooler, twin 70 bb turbos, aeromotive eliminator pump, -12an all the way, 5g cell, then all the other bs that goes along with this bs, lol.

    I'll take it down the road later and find out, or at the track and post up.
    May have less rolling resistance than mine, but it feels about 3300 or so.
