    TBI Running Rich

    I have a 95 1500 with 5.7 TBI. It runs great when it is cold (for about a mile). Then it looses a lot of power and sounds like it is drowning in fuel; not too bad but the performance suffers. My SES light comes on if I drive for more than about 5 miles. I would have the code read, but it's a...

    How to change fuel injectors/o-rings

    In doing my Intake Manifold swap I also did some other things that made sense to do while I was in there. This write-up will focus on the removal of the fuel injectors, which also is the same if you are just replacing the seals(o-rings), the process should be the same across motors and years...

    Truck needs rings.. Or should I 6.0?

    My 03 5.3 uses about a quart of oil per thousand miles. And trans is weak. Would it be more economical to 6.0/4l80e swap it or rebuild the 5.3? Edit: Keep in mind I'm planning on tradong it for a 6.4 superduty or an lmm next year Sent from my leather heated ass

    Supercharger tuning + what gauges to run

    I'm hoping someone might have some input, as this is the first boosted truck I've ran. For those who know, I have a Whipple supercharger on my 98 K3500 with a 454. The current setup is 42lb injectors and a tuned Blackbox PCM by Westers in order to run the whipple on my truck. It's a canned tune...
