Hay guys, So just recently my truck started doing a pinging / knocking right around 1700-2000 rpm only while under load, 40-60% throttle, No visable smoke and runs good in the power band everywhere else... When it first started i had it on the economy tune on the PPE hot+2... Thought it wasnt getting enough fuel or something wasnt right so I bumped it up to level 3... Ran good for a while, but I didnt drive it much after i turned it up... Today i started driving it again and its still doing it... So i set it back to completely stock, and it still does it... Is this bad fuel, timing not right, or what could it be...
I took a quick video today, if you listen around the 10 second mark you can kinda hear it...
