I'm sure this is a subject of some controversy. Where would I find

not going to make a difference comparable to getting a Bonanza to run at

vs. 16 GPH, but going from 6 to 5 would be worthwhile.


The JPI manual -- while presented in a convoluted, rambling way -- is
very helpful.

JPI mentions GAMInjectors as required for the Lean of Peak method.

The argument is that lean of peak the temperatures are cooler than
peak and burns less fuel. Thus you prevent heat damage (which you
might see at peak or even slightly ROP) and save $ on 100LL.

As well, intern chamber pressure is lower/better point peaks.
