A few thoughts given this was your thread ; your engine is even leaner than John's running 14-14.5:1 AF nearly the entire run. While engines can make peak power at a pretty wide range of AF (or lambda -better to think in lambda as lambda 1.0 IS the same no matter what your fuel) ) , we use the extra fuel to thermally manage this combustion w our goal to make maximum power RELIABLY, this hurts economy(efficiency) and emisions a bit, but that most likely is not you goal when you bought all those Hot rod engine components.

The power (which is corrected SAE J1349 std look it up-you lose 19% according to this spec vs sea level-crazy high-get a turbo lol!) is not what I would expect given your engine's set up. We use a Dynojet in various clubs for Clubracing to set hp/Wt classes and police it , and readings repeat fairly reliably corrected back to this std at sea level, atleast below 3K ft where we race in my experiences(dyno goes to various tracks) . I suspect power levels will get better if you run it at say -.85 - .87 lmbda at PK tqe and a little leaner near pk HP- say .88-.90. Start rich, (with better injectors more modern ev6 style w higher flow 4 hole nozzle -flow tested matched sets we can provide) ) this is where an adjustable FPR helps. You can lean out slowly to a safe level. It will run hard much more safely there at those lambdas. Don't disable you knock sensors, it is hard to know whether your knock sensors are functioning correctly, without making them knock w poor fuel and or alot of ignition advance for a brief period high load but low risk say full throttle 3500 -3750 RPM. You unfortunately don't have this tuning flexibility w a stock ECU(vs programmable stand alone w often go to) unless someone is there live w tuning tools to try these tests live . You can however, make sure the engine is pretty warm so go easy on the cooling fans, get oil temp to say 200-220 F but know if air temp gets high, the ecu will pull out a bunch of timing , so a little air blowing on intake mass air sensor area is ok. If you see random runs where after several pulls and a little sitting the power will all of a sudden be quite off, like 15+-hp and tqe, it either has quite high head temps and is knocking, or high air temp, both pull out loads of ignition timing in your ecu and all stock Bosch ecus as a protection strategy.I read 6 degrees fist time it senses knock, then pulls out 6 more if not done knocking next cycle, that is tremendous, demonstrating how once it starts, detonation takes drastic measures to stop. You want that safety, at 11.4:1 as in my book that is too high of compression for street fuel . Know an "11.3:1" 964 when CC'd out is actually 10.4 ish by Porsche. So ignition your timing has to be conservative, especially if you cannot verify your knock sensors are working properly.
Check that your throttle is going 100 pct full as I recall once n a V ram clients car , they attached the created linkage in the transplant to a connection point(maybe cruise control) where it went only about 80% throttle and the power was way off, A/F ratio or lambda curve was also. Your fuel curve looks alright, but worth checking. Also make sure the system goes in to WOT mode on the Reso flap(s) in condition 3 shown prior(I didn't verify that posts info) , and that you have the big multi balled reservoir vacuum chamber these come with so it can actuate all these V ram valves repeatedly and correctly. Maybe watch those vacuum actuated levers on a pull or put a Go pro there is too scary to have your face there(been there lol) . WE watch ign timing this way w a light on the crankshaft if we suspect timing is being pulled out from knock(watch your hoodie strings or T shirt don't get sucked in to the fan-not lol done that) Perspective- Typically w good headers and exhaust, on a stock" 993 3.6, and good fuel, we can get out what Porsche rates these flywheel at the wheels. This would be 270-275 wheel hp on a dynojet SAE corr, on a 3.6. Your's should easily be that w cams and a 3.8. I would find someone in your area w a Good audio knock detection device to monitor while you are tuning this if you are going to get aggressive on ignition timing, I read you can piggy back the stock sensors so your 993 ECU can still share the info.

Good luck

I'd say from shape of your Power curve the Tqe being so high at low RPM 2500-4K, this is where V ram shines and make a great streeter package(though really heavy) and your system i swokring properly in that range. Check the rest at higher RPMS WOT. .
