It sounds more and more like TFI to me, especially if you have 95k on the motor.
With your setup, "lean" is almost certainly not suspect. You aren't making that much power.
Do you know how to troubleshoot your ignition system?
Do you have a FPR guage to verify good pressure?
Have you checked your coil?
Have you noticed a "miss" under high load (i.e. high RPM) that becomes more pronounced above 5k RPM?
I assume you have the stock E7 heads and 19 lb injectors?
