Thanks for all the info,

Howard,
Thanks for your kind words.
When doing back to back tests to establish a trend I always recalibrate ignition and carburation.
I actually had an article on exhaust sent back to me by a so called tech editor of one popular magazine telling me the tests were invalid because I made more than one change - the exhaust and the carb jetting. Not only did this guy support his argument on the no more than one change idea but also he claimed that very few hot rodders would recalibrate after making such a change. Therefor my meticulously done tests were invalid.
Cammer,
I have lots of tests on various forms of coatings, some delived, some did very little and some actually were of negative benifit. I would like to get your take on the 'failures' here as they are often more interesting than the successes.
How about it???????
