39 mpg @ 80 mph? Thats impressive! Is that just the computer average or did you fuel up and hand calc to verify?

How about doing a test like this:

Begin with a brand new set of OEM plugs and a brand new set of the Pulsars, then...

1. Dyno with the OEM plugs
2. Swap in the Pulsars, then Dyno
3. Repeat 1 and 2 3X and do all tests back-to-back.

This would be possible if the cars computer would adjust extremely quickly. the cars computer has to learn new fuel trims and new timing with different spark plugs everytime. so doing it back to back would be pointless and wont have reliable numbers. this is why I've tested a pre-learn stage then later on a learned stage dyno test.

No the ECU as long as you didnt take the batt cable loose can learn the new fuel and timing in mil seconds , there will be little no no fuel changes at all with changing plugs

The only way to do this test properly is

NEW OEM plugs installed on the dyno just like the plugs your testing , just installing a new plug even if it is the same plug thats already in there will make petter HP
Then the other plugs installed and dynoed new


I like the Autolite AR and XP plugs

I was the first to test the AR series Autolite plugs they did so much better that did an artical in the MM&FF Mag about them

The Autolite AR series has out done every plug I have tested them against over the
years on my Dynojet dyno and they in most cases always will with the cut back wire vs a STD wire as it exposes the kournal to the combustion sooner and more efficient
