Single Turbo Lean @ High RPM

What's up everyone, I have a 93 RX7, Large Streetport 13b, Single T76 GReddy kit, 550cc Primary, 1600cc Secondary, Walboro 255LPH and an Aeromotive FPR. Car is on wastegate boost of 12-ish psi. The car runs pretty good, but it has a few odd spots. For instance, at a WOT pull and high RPM, the car has an A/R of 14 or so, and if I cruise at 70mph and keep my foot in 1 spot, the car starts to lean out around 15 - 16 AFR and you can feel the car slow down like im barely on the brakes... Here is a DropBox link to the tune and logs if someone would be so kind as to help me diagnose this issue
