I installed Gami injectors in my Lyc 540 in my Turbo Saratoga about 8
months ago.  The results are exactly as advertised by Gami.  George Braly
has done all of us a favor by bringing some very old operating (i.e large
radial engines) methods to help modernize our air cooled horizontally 
opposed engines.  Until Gami's were available, we HAD to operate on the
rich side because pre-gami engines run rough on the lean side.  Now with
properly configured injectors, all cylinders peak within 0.5 gph and do not
run rough.  In fact my engine can be leaned smoothly up to the point where
it will shut down.  Cylinder head temps and EGT are all lower naturally
since the engine is producing less power when leaned.  However, you can
regain the power by adding manifold pressure up to the point where you
regain the same airspeed as on the rich side, and then behold, the fuel
flow is less and the temps are still less.  Thousands of operators can
attest to these results.  "Leaning with Gami's" is not like in prior years.
 All of the old arguments of how to operate "rich or lean" do not apply. 
However, do not try to lean aggresively without balanced injectors.
