Dom,

I'm sure the most common cause for this is a change in ignition timing. &n= bsp;I assume the mechanic left the Lightspeed system alone, but did the nor= mal routine of resetting the timing of the mag. If the two timings ar= e exactly the same you will likely get the same drop on each, or maybe a li= ttle less drop on the Lightspeed. I've observed that most annuals inc= lude resetting the timing, but rarely will the mechanic state what it was b= efore the change, which would be very useful information. I'll bet he= advanced the timing of the mag by maybe 2 degrees. Just a guess :-)<= /div>

Been wondering why. Changed my= iridium plugs two days ago just as a starting point but no difference.

So thought I would ask the experts herein.

Thanks
