Good afternoon everyone,

 

This past week my vehicle situation has changed and I have been driving my 99 daily.  Since I have not driven it much this winter in the cold I don't think it sounds right.  I can hear a knock or a rattle noise when driving it and think it is either a fuel knock or timing knock and hopefully not something else.  The noise does not increase with rpms, but it is there. I believe the injectors are stock with 174k miles and the truck has a Quadzilla XZT+ chip.  Both videos were taken with the chip in the "timing" setting.  I have turned the chip to the off setting,  the noise is there but faint.  I have included a couple video clips, what do you guys think?

    Well today is a good day.  Got my 100hp injectors in the mail from DAP and found a Quadzilla Adrenaline local for sale.  I've flashed it with the most recent v2.7 tune from here.  Will be a few weeks

    Just a little update.  Truck has been running fine with what I call a fuel knock.  it still sounds like above on colder days, but I hope to fix that in next few weeks.  I ordered a set of 100hp inject

Dripley - I have not tapped the pump and have only run the quad on level 2 or level 3 thus far, but I have zero smoke even under heavy throttle.  I have a slight haze but it vanishes quickly under WOT.  The DAP 100hp VCO injectors are clean.  I'm sure if I turned quad up and tapped pump it would smoke, but I like the clean power.

 

I have ran Mopar1973man's economy tune, mid injector tow tune and Me78569's medium injector daily tune.  I am currently running the medium injector daily tune and love how the truck reacts, even on level 2.
