Ok.. Im sure you guys have gone over this a million times before but I cant seem to find the answers im looking for.

HOW IN THE HELL DO I TUNE THIS COMPUTER?!!!

Is there some sort of fuel tuning class that im missing out on at the community college or something?!

I have all of the initial setups done and everything is working fine but when I read the directions for the "airflow correction crap" I just get lost. I understand what the afc does and how is works to an extent.... but how in the hell do you guys figure all of this stuff out? I dont even want to play with it because I dont want to screw things up.... but on the same note, I still want to learn how to use this thing so that I dont have to depend on someone else.

Here's a list of my mods:

Recently rebuilt and streetported motor.
TID
Racing beat FCD
Ported turbo and wastegate
3" down pipe and strait exhaust all the way back
550 primaries and 680 secondaries
Profec B Boost controller
SAFC (that i cant tune)

So can anyone show me how to get started with tuning my AFC? Im assuming you would want to start rich and then lean it out from that point but I guess im too scared to even mess with that. I have an AF meter but is not a wideband.... I figured as long as I know that im not running dangerously lean im safe until I can invest in a wideband.

Can anyone help?
