Running rich and loss of power after 4k Had the car dynoed, its running rich, car has 80k miles, plugs were changed around 40k, vented optispark, ignition coil, and module have never been touched. I have no idea why its doing this.
Here is the dyno slip and a video so you can listen to how it sounds:

At part throttle yes.
The stock tune is set for mid 11s around 4-5k rpm at WOT. Looks like you are low 11s on that graph, but there is always some variation.
