Default Car Shudders when i shut it off??

Just flashed a new map to my car and only drove for a few miles nice and easy.
When I shut it off the car shudders, is this normal for a new map?

I've been told it may be the CAI i'm using, it's an Injen. Any other ideas? Looks like i might have to commit the MAF scaling thread to memory, and go that route.

Intake was on when i bought the car, never shuddered. I've owned the car for almost 4 years. Flashed the map, drove the car down the street and came back and shut if off and it
happened. Been running the same map since Monday, doesn't really make any noise, and it does feel like it's coming from the passenger side.

If the car didn't shutter before the map reflash, its not the intake unless he done some MAF rescaling but I can't imagine that he would for a STG2 map. Flash it back to stock & see if it does it then.

Log the fuel trims at idle. If the car isn't having trouble keeping the AFR at 14.7 then it isn't the map's fault.
