more tuning questions

[BigT]

I have mitsu evo 8 injectors which are "advertised" as 560cc, 190 pump, stock fpr, and a b16g. Since I picked up an AEM wideband, I ditched using the pockletlogger for tuning. My idle is between 14.9:1 and 15:1 and during normal driving(up to about 30% on the tps) the guage sways between 14.4 to 14.9:1 which good, no? AFC settings on low throttle are in the low 20's across the board. Now the weird part. My high throttle settings from 4k to 7k are -27 and the AEM still sees that i'm rich. As soon as I go WOT, the guage pegs rich and then wont register. The AEM only reads as low as 11:1 hence the reason it not registering. Now, i've heard from many people that evo injectors do flow more than 560cc, ranging form 580cc to 600cc. -27 is getting me a little scared. Seems kinda lean to me, but this wideband is telling me otherwise. Are these injectors infact that friggin big? Should I just keep leaning it out till I get a reading on the wideband? Is having an external wastegate dumped out messing with the readings? Last time i went to the track, i trapped just shy of 101 on pump and 19psi which is telling me i'm making shit for power considering my mods. Give me some insight.

Always double check the plugs if you have any doubts. But the aem wideband is very accurate. That's one of the things that I didn't like about the aem gauge, it doens't read lower than 11. Take some more fuel out and see what it does.

really mine reads as low as 10.0

yea its the older ones that read 11 and up i got one.

Generally I recommend between 10.5-11.0:1 so it sucks that you have one that won't read in that range, you could just keep going, -2 at a time and see if you can get it to 11.1-2, then add 4-5 back in and see how it runs. Is your maf hacked at all?

I agree with Mike...when my car was running, I kept it in that range with the techedge..
