SVOboy -
I have a free set also (free stuff!!!!!!!!!!). Here is my current plan for testing them :
1 - Tune-up my car and put in generic brand X spark plugs.
2 - Reset ECU/PCM.
3 - Drive for two weeks and make notes of the weather conditions along with the MPG.
4 - Go to my mechanic and raise the car up in the air.
5 - With the car in the air, put the car in 4th gear at Y MPH with cruise control on.
6 - Reset the scangauge and let the car drive at Y MPH under stready-state conditions for 10 minutes.
7 - Take down all scangauge readings.
8 - Install pulse plugs.
9 - Repeat steps 2-7.
In this way, the car will have a before and after set of readings. The two weeks will allow for normal driving with all it's vagueries. The two weeks will also allow the ECU/PCM and the plugs to "get to know each other". The "up in the air" test will be an attempt to isolate an MPG difference from all the other external factors.
I have just finished my yearly tune-up, so now I have two weeks to wait. I may wait for three weeks, because we're due for a week of rain in LA this week (go figure). My mechanic just switched spark plugs, so I won't know the current model of plug until we replace them (I didn't ask him, my bad).
