OBS 7.3 backfiring?

I was just casually driving down the road today doing about 45, gave it some throttle to get up to 50 and boom (sounded like a gunshot) and it continued to drive fine, got home. Shut it off and it fired right back up. No rough idle, no fuel or oil in coolant or anything like that. It did blow my one intercooler pipe off. Any ideas what it could be?

You sure it wasn't the boot blowing off? Cheers!

Probably was the boot, a backfire on something with a stroke distance as large as a diesel would probably lift your truck off the ground (J/K). But Id assume if it actually happened, there'd be damage.

Re: OBS 7.3 backfiring?

When a boot blows it is normally LOUD. So I could see why you would think it was a backfire.

As stated, a backfire would likely cause some noticeable damage.
