I already had stock stuff in there. Randomly changing numbers is even more risky! That's why I chose to compare to a performance vehicle, go through all tables and select only the specific upshift parameters to modify. Once I observed the differences in performance I then found a middle ground. It's the cost of experimentation. Can't sit around waiting for someone else to give me the answers, right?
