Well I installed the DirectHits system in my truck and took it for a spin around the block. It definately feels more powerful, but it was just a short drive so I'm still allowing for the possibility of it being just psychological. We'll find out for sure tomorrow when I drive out to my friends' place in the Snohomish valley. I'll measure the mileage I get from the next couple tanks of gas and post my results.
BTW, those Brisk plugs that I mentioned in an earlier post aren't available in a non-resistor flavor for my rig, so I got the Brisk plugs that use a normal electrode.
