Kyle,

First thing... please double check that the MAF sensor is not installed backwards. The arrow should be pointing in the direction of the airflow, towards the throttle body. I just ask because it can cause the symptoms you've described. Also check and make sure the are no air leaks in the tubing/boots as this can cause erratic MAF readings and a subsequent lean condition.

If that's all good, then I can make some minor changes to the MAF structure to help resolve the lean condition. It's just unusual as the changes we've made should be working just fine.

As to the shifting, if the MAF sensor is not reading correctly, the load calculations will be inaccurate and this will severely affect shifting. Again, if the intake setup looks cool, we can make some adjustments to correct the shifting.

Thanks.
