OP/all - I’d found this thread bc havjng the same issue on track only (w some streetvexamples but less profound. Was just posted in a Camaro 1LE FB group. Can anyone post the full TSB? I posted this in the thread above as well.

###

I’d like to share a little message brought to me by someone smarter than myself. LT4 guys, pay attention. If you’re anywhere near the Detroit area, let me know, we’ll be doing a bunch of them.

Alan,
FYI… ICHE purge tool bulletin which is published to dealers - 18-NA-291 TSB
You will want to perform this to all Camaro w/LT4’s. (including your car)

SO, this bulletin is put out to get air out of the stock intercooler circuit. If any aeration has occurred, intercooler temps could spike causing premature spark retardation.
