To check your AFR, you will need to get a 02 sensor bung installed in your exhaust, prior to your primary CAT which is a total B**ch. Then get a wideband datalogger such as this:

You're probably running a little leaner...but nothing I'd worry about considering the size of your pulley.
But you would definitely get a benefit from getting a custom ECU Dyno tune.

The dyno was a dynodynamics. The car is faster than another c32 with the same mods I can guarentee, I don't know what it ran stock. Never raced it stock. I am the third owner, maybe the previous owner did something??
