You get extra style points for doing all your work poolside.
Do you have any concerns about the MAF or any other the other sensors reading correctly? Do they need to be in the correct "spot" in order to read right?
Periodically my BMS intake causes a CEL for too high of airflow, can't imagine what this one would do! But I also don't have any remap of the ECU to expect and handle the higher flow... so not a big deal, easy fix with another upgrade.
