Although I don't condone nor particularly endorse Loren's abrasive style....I'll bet that in his own charming way...all he's trying to do is enlighten some of us to pitfalls such as :
1.) how do you know what you "don't know" ? ( aka...sub-audible detonation or pre-ignition), without measuring tools or prototype test results?, i.e. .....how can you quantify the "danger zone"? Especially true since this is a moving target with engine load, rpm, ambient temps, etc....all being factors. ( the counter-point, of course, is that Porsche would not market their unit right "to" the ragged-edge of reliability. There has to be some "room" for mods that tuners and their customers have always willingly accepted as a risk. Question is ..how much is reasonable and understandable?).
2.) why do we show understanding ( and therefore concern) for overly high CR vs keeping single plugs...yet we don't grasp ( or want to grasp) the relatively similar effects of aggresive chipping ???
This is beyond tech issues and begins to touch on the human psyche and emotions too. The fact is that a chip is a relatively inexpensive mod to make...and the ease with which this can be done can lead to a false sense of security. Especially if you don't have a clear understanding of the chip tuner's design philosophy. Conversely, twin plug mods, especially when done in conjunction with a major engine re-build...is lotsa $$$...and those posters will be *very leery* of any unwanted destructive effects on their precious motors. They've typically been "sensitized" on this issue a bit more.
Of course...I'm not a psychiatrist, but it helps to be one to post on this topic (... I only play one on TV.....)
