I think you have misunderstood my comments. I am not judging you at all. You ask specific question and I answered them with 10 years experience driving the TR. I spent the first two years doing what you are doing trying to get the best performance. Everything I have told to was to try to help you. Lots of guys on here gave me a lot of bad advise. My advises to you were from real experience. My best performing set up was BB 25 1 large plug set at 1 3/4 - 2 1/4 below pad. 6" manual jack plate. At higher altitudes I would remove the plug. The hole shot will be slow but it will be easier to drive at WOT. Altitude matters. My experience 0 - 1000' not much change but when I would run at 1200 or more it really affected performance.
