Tuning for Injen start-up issue
I bought my IX MR w/ an Injen intake sytem already installed, so need to flame me 
I have been able to tune back up to 22psi from the 18psi that it was hitting when I bought it, and I am very happy with the power right now, and I'm just making a few adjustments - thanks to all the great info on here.
My problem is at idle...The car occasionally wants to stall at start-up, or if I stop and I'm idling for a while. A/F is very high when this happens - up to around 18 if I remember correctly. What is the best way to adjust this - add fuel at the 500 and 1000 rpm's in the very low load cells?
Thanks

Before you add or take away fuel, you probably want to know whether you are rich or lean.
If the car is warm and you're at idle, it's in closed loop.
If you're just starting up cold, it's the open loop map.
