Loren:

I'll bite and offer a comment....

I don't thnk there is as much difference in the attitude of people on this board as you think...when comparing the damaging effects of:
- too high compression with single plugs, and
- running chips with more aggressive timing and fuel delivery maps.

Agreed....both ...when taken to an extreme...will cause the same sorts of problems. You seem to imply people are turning a blind eye to the "chip" effects"... yet are oddly "aware" of the single/twin plug goodness when going high compression.

Maybe it's this Loren.... maybe it's a matter of degree. In much the same way that going from 9+ CR to 10+CR is bad for a single plug engine with today's gas.... the same can't be said if we went from 8+ to 9+ CR. That wouldn't demand a change to twin plug as assuredly as the former case.

We can make the same analogy on chips. Going TOO FAR in aggressive mapping indeed causes engine distress...but going only a little bit aggressive from a baseline that may have assumed 87 octane fuel ( like the 84-85 Carrera's)....similarly won't make the engine self destruct. The factory did the same thing in their various chip offering up to and including the "cup" chip.

You say "we're not listening". Maybe "you're not listening" in that all chips mfgrs don't use the *same* level of aggressive tuning. Some inch up in a more conservative manner and won't land you into the trouble zone....as you keep telling us "all" chips will do !

I'm sure you'll respond to tell me how very wrong I am....
