I have an aem ems and it was tuned at 14 lbs. I drive the car everyday to work and have it set at the low boost setting of 7 lbs. Also when the car was tuned it had an MSD box installed in it. The car seems to run very rich. It says it is at stoch when driving but the inside of the car smells of unburnt fuel. Do you think b/c I am running at a lower boost then it was tuned for this would cause the richness. My theory is it was tuner to provide a certain amount of fuel at the specified boost. But since it is not running at the boost it is just dumping fuel in and not automatically correcting the problem? I am new to this so any help would be great.

You'd be 100x better off posting this on the AEM EMS Forum.

Personally I think it's going to come down how the original tuner chose to tune the fuel maps and how they made use of the fuel correction tables in the EMS.

At lower boost the computer will deliver less fuel, just like it delivers less fuel if you put your foot down 1/4 of the way vs. full throttle. Your tuner just must have tuned WAY rich to be safe. He can smooth it out for you if he knows what he's doing.
