I was wondering if 2.75 was currently used.

Is the loss of toque with larger pipe due to a mismatch between ECU Calibration and part. Obviously most manufactures make products that match the factory calibration (AKA Stock Vehicle) and not for max power after a proper tune. Have manufactures and tuners tried to tune with a larger system that could prove this? With only flashes available engine performance would seemingly be limited.
