Danny,
Then = I don't entirely understand, as running 2400 at 10,000 puts you at about 62= % power and and at 100 ROP you should be burning about 10 GPH.  So if = you are running 8.5 GPH you must be running LOP, or at least at peak, alrea= dy.  Yes, you will likely save about 1 to 1.5 GPH, or about $5 per hou= r.  So to save the $1,000 of the course you will have to fly 200 hours= .  Not many, actually.  Plus you will be getting better range (fe= wer fuel stops and the fuel stops you do make can be at lower fuel cost loc= ations), longer spark plug, oil and engine life.  Cleaning 8 spark plu= gs costs, what, maybe $100, so every little bit helps.  When running ROP I could barely get 100 hours between cleaning and at LOP they will eas= ily go 200 hours.  I think if you add up all the savings you will find= that the course will pay for itself in 100 hours if, that is, you leave ta= king full advantage of the course.  And that's not counting the value = of the piece of mind that comes from knowing more about how the engine oper= ates.  Again, just my opinion.

= Gary, et.al,
I certainly can=E2=80=99t speak to what others = are getting but I have GAMI injectors and my engine has been flow balanced.=   On consistent 2.5 hour flights from VA to MI I indicate about 8.5 to= 8.8 gph.  This is backed up by the amount of fuel I replace in the ta= nks which is about 22 gal. =E2=80=93 never been more but sometimes a little= less.  I fly at 2400 rpm and whatever MP I can get (usually about 21= =E2=80=9D) at 10,000 ft.  So again, for me, the expense of this $995 c= ourse just doesn=E2=80=99t work out for my ROI.
