still running rich at wot???

[TurboTJ]

I have been running very rich at wot throttle. After a previous post, I swapped out the IAC and bought a data logger. I put a new IAC in this morning and it didnt fix the problem. It did make it slightly better though. I also cleaned the throttle body. Timing is 10-12 degress at WOT and AFR is 10:1. There are no boosts leaks and no CEL. Any ideas what could be causing this??? I have an evo III 16G at 9PSI with a 32" x 12" x 4" FMIC and full 3" exhaust.

thanks for the help!

I agree. WB02 is one of the first mods you should get. I learned the hard way trying to tune my Jeep and running it lean for 3 hours at 5PSI but luckily only warped the exhaust manifold.

I think I am running around 9.5:1 but my AEM WB02 bottoms out at 10:1 so all I know is that I am richer than that.

THANKS FOR ALL THE HELP!
