I never said people who use HEI are wasting their money. Five
out of my 7 cars use high energy ignition.
My point is that performance is relative. Most everyone who
tries out an HEI solution on a DeLorean are doing so because
their car doesn't run right. Of Course they are going to see
a performance improvement. Relative to a poorly running
car with old parts, a new set of OEM parts would be a
performance improvement. What I would like to know is
the relative performance difference between the HEI solution
and a properly tuned car running original parts. That is the
performance difference you are Actually Getting.
And your analogy misses the point I am trying to make. There
are very clear, measurable differences between an internet
connection across a phone line and broadband. You didn't
upgrade from a worn-out phone line that was only getting
38Kb bandwidth and go to broadband that gets 60Kb. You
pulled the engine and gearbox and changed the whole works.
