Default Gap on the spark plugs???

I regap my Denso Iridium spark plug from standard .44 to .35, now my car early rpm feels better. And overall the power band of the car improved......does the gap on the spark plug really make that much difference. Does anyone have the same experience?

Default Begin with the gap recommended by Audi, then read this.

Default The gap that the plugs come are for "stock" boost, they are not sold as a "chip" gapped plug.

.040 is too wide of a gap for a chipped 1.8t that runs twice as much boost as a stock 1.8t.
