Well, I've been to the GAMI site.  Seems they only charge $1000 for an education on 520,s, 550's turboed, etc.  But nothing specific for us wee guys with 320/360's.  Then I went to the Far West Aviation web site for info on their power whiz wheel - not useful because it doesn't represent my engine characteristics.  I have performed the GAMI lean test although I don't know what the power setting I was using at the time because I can't calculate the engine HP let alone the thrust HP. I still don't have a "calculator" for HP.
 
The lean test showed I have made the right adjustments and the individual peak cylinder fuel flows are balanced close enough.  Of course, I am using the VM EPI 800 for temp measurements - that means the computer jumps in 8F steps and displays in 10F steps.  Ugh.
 
If anyone can help:
 
I/O 320 with ECI TITAN Cylinders
Front mounted throttle body with max ram air rise at 200 Kts.
Fine Wire plugs
Lasar Electronic Ignition (IO 360 Map), 20F higher CHT, 70-80F cooler EGT
9:1 pistons
Ram air fed shrouded .22 dia. injectors
 
15.4 gph at 2700 rpm (takeoff WOT power @ 700 ft msl), ram air negligible.
 
For example, What power % am I operating at under the following conditions:
 
9500 feet, -1*C, Dalt 8840, 169 IAS, 192 TAS, 22.4 MAP (WOT), 2510 RPM running 50*F LOP, 7.4 gph?
 
Help!
