Yes on the analyzer but not necessarily for leaning, more for advanced warning of impending failure while it's still in the inexpensive stages of fixing. Invaluable for the early detection of a leaky valve when some X-66 and lapping compound will fix the problem. Experiment on the injectors, you might find yourself close enough that you can run stock, both mine do just fine with stock injectors. You don't need any fancy software, just a basic understanding of analyzing the raw data, and that information is freely available. You can fly like has been done on your engine by some for 70 years and do a top mid time and overhaul short of TBO, or you can operate like others who learned during WWII from Lindbergh and run LOP getting your engine through to overhaul without burning up a set of valves or two in the process.
