Sorry about me writing "Impression", I meant running rich WILL give more power/performance. That old resistor across the o2 sensor trick.

I'm with you now.

Running rich does not actually give you more power, it's a common misconception. You actually have to run very slightly lean for the best combustion, if I recall correctly. You want to run richer in a turbo application so that the extra fuel acts as a coolant to prevent detonation.
