I have been trying to tune the car since installing the AEM Uego wideband and have been having some issues. First of all the car goes really rich from about 5k to 6k no matter what adjustments I make to the fuel sliders and I do not know why. After that the wideband just keep readings leaner as the rpm's increase. I've attached a log, please check it out and let me know if you can pick up on something. Thank You

The car is a 98 Automatic GSX and the relative mods include: FP3052, FIC 850s, rewired 255lph HP fuel pump, Aeromotive AFPR, 3" turbo back, fmic, AEM Uego wideband, etc.

Are you really running about 9.6:1 at WOT?

Im no expert with DSMlink ;), but arent you supposed to be seeing 16 degrees of timing and anything less is a knock issue or coolant temp issue?

The dsmlink estimated a/f ratio is reading in the 9 area but the wideband is reading in the 11 area, this is part of my question. And about the timing, I lowered it some in order to run more boost.
