Here are the dyno graphs from the dyno run back on the 17th. This was done on a DynoJet.

Nice. Looks lke you need to get something to lean those AFRs out after bost kicks in. It almost looks like a boost spike, but it's just dropped to rich so fast.
 
Yup, I have an Airflow Logistics AFC coming to me early next week. I'll dyno again at stock boost with the AFC in place to document the difference. Then the MBC will likely go in.
 
Depends. The dyno shop I go to puts a high cfm fan in front of the car so it doesn't over heat. Which means the FMIC would benefit also.

Ion FMIC, Injen CAI ... not like those do anything with the car sitting in a dyno bay any ways.

Well, yeah, but I can't see blowing hot 91 degree air over the FMIC doing anything for performance.

Yes, it does need tuning very badly. I have the Airflow Logistics AFC coming early next week.

I've been keeping out of boost and shifting pretty early. I've been getting around 30mpg combined city and hwy.
 
You think his is bad here's mine. Starts off lean as all hell then boom plummets to ungodly rich.

It definitely is. I looked at the exported data and there are sections where it's at 10 flat, so it definitely goes below that.
