Attn: Todd AWE - Update on 17535 & 17537 Fuel Trim Too Rich Banks 1&2

Just unplugged the MAF and took the car out for about 15 minutes or so and the DTC's did not return. The only DTC I got was MAF Signal Too Low which I assume is because of the MAF unplugged.

The car ran alot like it did the day when we thought we had everything fixed. Boost seemed to come on a second time around 5k and pulled fairly smoothly, a bit jerkiness up high, I assume this would be the default air / fuel mixture not being just right due to the lack of air metering.

I didn't have a chance to log anything with the MAF unplugged yet. Do you think it's safe to say it's most likely the MAF causing the DTC's ? I assume there could still be a problem with N75 as well, but the MAF seems to be the most problematic at this point.

I will plug the MAF back in and take it for another spin and see if the DTC's return.

Your thoughts ?

Thanks again for all of your assistance, it is much appreciated.
