Today's update: Unfortunately the 2.5" ID (+ 14% surface area) kept trending downward (Lean) and started to feel a little flat. Just a tad too big on the ID. I sleeved the MAF tubes today to bring them down to 2.42" (+ 6% surface areas) and things felt a lot snappier. As you can see, 1/10th of an inch makes a big difference here. Long term fuel trims seem to be trending back toward Zero. I'll run it this way for awhile and see where it goes. I have another sleeve available to take it to 2.37 if I need a little more....
