I think Loren has a great deal of knowledge but trouble accurately communicating this knowledge (without getting condescending).

For example, his discssions regarding chips imply but never explicitly state an issue with them that is a pet peve of mine, which is: it is impossible for anyone setting up a map for a chip to "get it exactly right" without quantitative feedback on the engine'e performance. This is (at a minimum) having accurate wide band air-fuel ratio vs RPM data and more preferably, A-F and dyno run data.
Now you can make an improvement on some maps based on experience, but it is simply imposssible to get it close to exactly right without doing multiple iterations using real data as feedback. I know because I have done it (many times).
