I installed my CA spec X-charger a couple of weeks ago. I am running the 91 octane tune. Everything has been just fine. Except: when I stop at a light or stop sign, the rpms dip down momentarily and this sometimes stalls the engine. It has happened I think 4 times now. Anyone have the same experience or any ideas what this might be?

Vacuum is 19.5 to 20 at idle. Haven't tried to reload the tune yet.
I read on a Ranger forum something about the decay rate of the IACV (Idle Air Control Valve) that solves it if changed in the tune, but I'm not sure our engine has an IACV.

The new tune seems to have solved the idle problem, but I mentioned to Doug that I had a little pinging. Now the throttle feels a little "heavier," like I have to depress it more to get the same acceleration. Maybe my imaginiation. Maybe after it "learns" it will feel differently.

Reason: spelling
