My personal experience with big tuners is that sometimes they try to be a little secretive to protect their knowledge. The fact is, information is power and if you give it away you will be replaced and not needed. However, I can apply this more as a mechanic. Parts changing and factory vehicle diagnosis is a limited knowledge ( I can say this because I turn wrenches for a living and even though one never stops learning, compared to tuning is is minuscule - you will not find many brutes with barely any communication skills making a living tuning...)
However, in my opinion a real good tuner has absolutely no need to hide any info. If you are on to anything more that basics easy to stumble across on the Internet, chances are you are so far ahead and constantly evolving that it is not possible to keep up with you. Having access to info is NOT the only thing needed, you must have a certain type of mind and background, which many of us do not possess. In your own words, there are no magic numbers or procedures. This could explain why this forum is so friendly and helpful. I could barely achieve anything without constant help and have no hope what so ever for my dream future tuning career without a billion zillion trillion "bra-zillion" more help posts. Just my two cents... Thanks again all!
