Dialing in low RPM airflow, in MAF and SD, truck wont idle now.

I tried to find a thread on this.. Couldnt find anyone else with the same issue.

I got closer to getting my MAF and SD tunes both near lambda.. I always multiply by half..

My cells in the idle range were showing lean, both in SD and MAF.. So the last time I tried to make adjustments in either mode, the truck wouldnt stay running. Dies as soon as I let off the pedal- even with idle set at 1200 rpm.

I got a cam with 228/232 duration @.050

Not sure what's going on... Any ideas?

Probably need to increase idle minimum final airflow

A 20% increase worked. ��
Now if only I could get it to idle below 1100rpm ��
