As for you not wanting to drive with a lean engine, I totally understand that. I've driven with a lean engine when I installed my SC for 7 months. No damages whatsoever, but i'm not saying that you should too. Your engine could run normally when it's warmed up, just like how mine was.

It is the CARB tune. He has said that multiple times, so Edelbrock did the tune.
