well the correct way to dyno the car unlocked is 3rd gear, using tech2/efilivepro to unlock(or)lock the verter & lock in the gear, then nail it. the verter will flash or not and the run is done.
course you wanna be out of gear when the dyno ends, so the inertia of the dyno wheels doesn't unload into your drivetrain (strapped down) which can break things..

Here is my car with the M6 with 6psi then changing nothing but putting a TP4200/TH350 and 9" ford with a 3.70. The rear has drilled/star flanged axles and a lightened spool so it doesnt take a lot to turn the 9" Is still run 97mph in the 1/8 through the dual/dual exhaust (all stock except for headers, LS1 intake and all) so it doesnt bother me much - just need to get the 60's down a little..

No dyno tricks were used (short belt, cutout, etc). This was w/ 29 degrees of timing.

Alittle freakish?
Damn those ls6 heads must be working pretty damn good. Most a4 guys with that cam and stage 2 heads are in the 390-405 range locked depending on boltons. Those are very impressive #`s. Congrats on a great setup

here are mine, but you can also just scroll down to see them...but for the lazy people here you go: https://ls1tech.com/forums/dynamometer-results-comparisons/147032-tsp-heads-cam-dyno-s.html
I got my results today from Greg Baish at Livernois Motorsports (formerly Detroit Speed Works)...This is on a Mustang Dyno and through a built 4L60E and a multidisc loose converter, unlocked...it made 403 rwhp and the same torque. The peak number aren't great, but it makes perfect flat power throughout the area under the curve. He said it was a perfect 12.6 A/F throughout. I am getting the car back this weekend and will start installing the nitrous (150 wet shot to start and probably get everything in line for a 200+ shot). He said it would be about 440+ rwhp/tqe on a typical Dynojet. Shifts at 6500, makes peak power at 5800. Its a MTI built 382 stroker, and I changed tha cam (didn't go big enough!!! only the X1) and upgraded the fuel system, changed converters, etc. I was running 11.61 on drag radials last summer (FULL weight.and then some, 3.23 in stock 10 bolt, stock auto, etc) so I would like to see some low 11's on the 16 X 8.5 Weld Prostar XP's with ET Streets on the back this year. Nitrous should put me solidly in low 10 second range I assume. Still drives like stock and idles perfectly (I had a 114 lobe on the X1 cam). Remember its not peak power that always wins races. There are a couple of 775 rwhp and 630 rwhp turbo cars runing 11.3 to 11.8 at the track (not picking on them, just saying high dyno numbers don't always mean stellar track times).

397/382 on a small 554/575-112 cam just got a custom grind from FMS i hope it helps
i was runnin stock tb and 26lb injectors a/f was 12.5 lil rich --i shooting for 430ish
i also upgraded my lifters and oil pump--i only got 2 runs in "snapped the tailshaft houseing on the dyno "friggen 2:73 gears mph so fast" one small vibration caused it to snap--this was with the converter locked --
mods lid /cutout/lts/self ported heads/and the 554/575 cam

yeah i got the snapped tailshaft housing syndrome too on the dyno 
damn the mang.
i can imagine being locked in 3rd and letting off the gas would transfer alot of inertia from the rollers back through the rear end/tq arm onto the tailshaft. Did you throw it into neutral at the end of the run?
good #'s btw.

My numbers are in my sig. Just had the car dyno'd this week at RMS. 3rd gear pulls on my graph were messey, so all numbers are in 2nd. I am guess a little more octane and she would clean up. We played with some timing along the tune, Aif/Fuel was right were it should be. Those long pull's in third gear w/2.73 puts a little labor on the motor. The ported TB did give me gains which really showed from 4400rpm to 6000rpm. A peak of 6.5hp and 5.4TQ.
i got 286 hp and 316 tq locked on a dynojet with mac cats, and no cutout. it was throwing codes for egr and air beacuse they are extinct. i'll probably go next month and see how the ory and cutout did for me. i may also take the slp maf off and put on my descreened stock maf, and leave off my hypertech engine tuning.

that's what i thought also but alot of people think it's right on. i dunno. here's a thread about my dyno when i got it done. also i didnt use anything to unlock my converter on the dyno so it was locked correct?

the correct way to dyno, is to use tech2 or efilive pro or whatever and command the gear to 3, then command the tc to be locked or unlocked, then run.
in my dyno charts in my sig, i believe the tuner did the command 3rd gear, then command unlocked, which is why you see the baseline spike as the converter flashes, then you see the massive flash from post-mod/stall install.
i could be wrong, i can ask him. Either way the point was to baseline a before/after and it did indeed show me some more hp up top
little less than i wanted but i hear A4's its not always about the hp for 1/4 mile. If you notice my dyno, then go to http://www.converter.cc/dyno_shop.htm and see how their graphs look.
Seems like thats how your car should look like if you dyno it right (unlocked).
i don't do any runs in 3rd/4th to high rpm's locked up, cant afford the jail time, i dont think i will be locked up in 3rd/4th on the track either, might be too hard on my old tranny

Here are some converter numbers for you:
304wrhp with 390 torque
That’s unlocked with a Yank SS3800 on an all stock LS1 engine and LS1 intake.
Ran a 12.58@107 with 1.69 60'
I will be taking it to Ed Wright in a week or two for tuning.
