af's, running rich

[daneyan]

hey guys. just wanna know a lil about af's. i got my car tuned about a month and a half ago on an afc. right now i guess i lost my tune someway or the other cause i'm seeing 10:9 af's and 10:0 at wot. im running 440's and my fuel pressure is at 38-40 psi. should i get it retuned on a dyno or should i just get a street tune. i know it's rich also cause there's black smoke coming out the exhaust on boost and after lets say a hard boost run it'll sort of bog down. plugs were covered in black soot. need to get it running better by saturday just in case someone tries me at the supra meet. anyone around know how to street tune an afc should i try to do it myself since i have a wb. if anyone can help in or around the south florida area hit me up.

Have a friend ride along to make adjustments if you're going to do so on the highway. Alot better than looking down everytime after making a big 100+mph pull. If you're running really rich everywhere, try pulling a little fuel out across the board. You don't remember at all where your settings were?

IF you want to retune, try Gary at Speed injected. He did my car and it's running nice. He tuned the low for good fuel economy, plus he'll max out your tuned then pull back a bit for safety.
With 440cc inj, you should sit around 400rwhp on the safe side.
