A tuned injection system is key to running LOP. With typical factory engines, there are standard disparities between cylinders, which are acceptable for 99% of all operations. When running LOP, using the GAMI injecters(which they work with you to find the appropriate nozzle for each cylinder) are why you can make it work very well. I gave a guy a BFR in his C206 that did all this, and it was impressive. I would say that it does take some time to really tune it in, but the results are great.
