happens to me aswell, only when I am dropping from say 4krpms or higher and just completely let off the gas. Doesn't happen all the time but every once in awhile it will fall right down. I usually feather the throttle a little to avoid it.

 

log your idle learned value during the condition and post the results along with timing, afr, and map

 

My car is set up to idle around 1300ish for a few seconds in neutral and then settles in at
950-1k idle.. I thought it was kinda funky it did this after the tune, but I now figure that it's probably something that Mase built in to the tune in order to avoid these stall problems..

 

do you have a 1012 or a 1052?

 

A 1012.

 

thats a wierd issue with the 1012 then i guess... we tuned a car like that. it would die out the guy changed out to a 1052 and ever happened again

 

There are plenty out there running the 1012 without this issue so I think I'll look into it a little bit before throwing out the baby with the bath water.
