keep me updated on what you find with the single. Its possible your new sensor is the problem. The translator is typically accurate to +/- 0.5% or so and the OEM MAF sensors are typically no worse than +/- 2% although the manufacturer allows for a bit wider variance than that. To get something on the order of the 10% change you saw something is definately not right. When you switch back to the single test both sensors before and after and keep track of which is which. Do you know which one was your original at this point?
