yeah.... I would think any product/part/mod that improves combustion(thus causing the O2 sensor to sense a lean-burn condition), would have a mod/instructions to compensate for the change in O2 sensor signal so that the ECU doesn't "dump" more fuel in to compensate.....

thanks for this thread, I was wondering about them, and there isn't much info out there....
