I've been blogging my experience with tunes herehttp://www.fordraptorforum.com/f24/my-initial-tune-thoughts-35000/But I wanted to start a different topic. For those who understand what tunes do, can you share a little "under the hood" knowledge?I understand the differences between performance, economy and tow tunes as far as shift strategies go. Some tunes hold on to certain gears longer. I'm still not 100 % clear on the "faster" or "firmer" shifts, but that's ok. What else differentiates an "economy" and a "performance" tune? What impact does the fuel air ratios have on performance and how are they tuned?In other words, what is the difference between a 87 performance tune and a 93 economy tune outside of shift strategy? What other tweaks are made?I'm not looking for tuner "secret sauce". Just to understand a little mire as I try to decide what tune to stick with.
