So I'm kinda lost as to what happened, cleaned everything really good, vacuumed out intake ports, started up fine at first and then some rpm dipping, afrs are 15s-14.7 oil press is good
I'm glad your motor isn't hurt. I've never heard of spark knock at idle with no-load, I'd look at that intake closely. Maybe there was a good reason it was for sale?Guess what? Swapped intake back to stock and it's all good, it's just spark knock, that's crazy! That the boss makes that much of a difference

In that video, is it idling without the re-tune? Or is that after it was re-tuned? Also, of note, there isn't enough "self correction" in the system to correct for going from a stock manifold to the boss manifold. It shouldn't hardly idle at all, however, the blower is sending more air in at idle than without it.
Call out the guy at hp tuners lol. If you put one of those garbage throttle bodys on then ya it wont run right. It should be fine with just a boss mani. Sounds like the op had a serious vacuum leak the way it was idling. I have pinched a gasket on another car one cyl running way to lean and surging + misfire.
