yeah that's correct, but make sure you have had your computer resetted before doing anything, let the car warm up on it's own till it fully warms up and engine idles kinda smooth. then begin adjusting afterwards. i really don't want to get too detail with the tunning 'cause it gives me a headache just thinking about it. goodluck with it.

Uh NO! Automatically take at least 20-30% out on lo throttle at 1k. If you start the motor with no adjustments on the lo-throttle of the AFC you will flood the motor PERIOD! It will idle (if it even idles) like crap. You will probably have to keep your foot on the gas to make sure it doesn't die. You can't wait for it to warm up. By that time you'll have dumped almost twice the amount of fuel necessary! Just think about it for a second and this is PAINFULLY obvious. Quite possible fouling the plugs and burning out the front o2.

This is what you should do. Adjust lo-throttle to -25% across the board. Every RPM range. Leave hi-throttle alone. 0's across the board. Get a datalogger. Start the car ... it will probably run rough. Take a little more fuel out of the 1k rpm lo-throttle point. Keep doing so until it idles ok. Now take the logger and start monitoring STFT and LTFT. The ECU allows for +-25% for both values. Keep mucking with the settings so that the STFT isn't close to either boundaries and the LTFT is close to 0. This will need to be done after warm up. Then take it for a 0 boost spin around the block. Again watch STFT and LTFT. Apply changes to RPM ranges where too rich. After that is all settled then go for boost. You will most likely be rich across the RPM band. Monitor and then adjust hi-throttle setting accordingly. Narrowband o2 is very inaccurate so a WBo2 is preferrable. If you are using a NBo2 then tune it rich. You want to leave the hi-throttle close to 0 at the top end because you don't want to muck with timing that much.
