Data results should provide balance to decisions/choices. It's a good thing to put the question out to the forum because you will gather a bunch of opinion and data as well. Be prepared however, to hear what the majority of insight's can provide. A single mechanic can not provide the same level of experience that numerous people can ….thus the goodness of the forum
I run test pipes, Redline oil for engine and transmission fluids and after 40k miles and 2 years of running track sessions my car runs exceptionally well.
Just my opinion above…sorry about the soap box
