I have my 227/235 cam idling at 750 with a AFR in the 15.3-15.6 range In my choppy idle tune lol. Its terrible when trying to drive. Keeps wanting to die.

 

Did some more idle tuning and can now drive with my 750 rpm idle. Have the over idle set to -15* at 300 and under idle is +20 at 300. It actually makes my truck rock back and forth. I'll see if I can't get a vid one of these days.

 

It's all fun and games until you break an engine mount doing that. Then you have issues.

 

Lol, its not that violent. I work on getting a vid of it this afternoon.

 

If idling breaks an engine mount...your **** was already messed up. lol
