I think it's just a matter of time then you will feel the power increased. A lot of people told me that the ECu needs some miles to realize the increase in the air flow. But the HFCs are the one I felt as it was installed. I went to drag my car 3 hours later and got 0.3 better than last week

Just in case you didn't know. You first diconnect the battery to reset the ECU (plus due to messing with electrical componets). Install parts. Reconnect battery and let the car run (ideal) for five minutes to allow the ECU to get used to the different air flow. Then you can take it out and run to red line to allow athe ECU adjust to all settings.
