This.
Example of how well this placement works from my vehicle. This is strapped down on a dyno with zero air flow on the vehicle (worst case scenario) and warm summer conditions. Observing the injection timing also shows the DDE advances timing based on lower IAT's. Seeing the dramatic reduction in IAT's during the pull when the H2O/methanol kicks in is impressive, and also helps control EGT's.
