Default White Lightning's new engine break in on the engine dyno/turbo testing!

I figured I would post this up on here since it is pretty interesting stuff. I built a new motor for White Lightning with some help from Guy at SoCal, Exergy Performance, John (Fingers) and of coarse my shop. I was nervous about having another stock crank fail during my up coming 1/2mile race so we decided on a new block fitted with a SoCal/Bryant Extra Narrowed Rod Journal billet crank and Carillo rods with 15:5Comp Oval Race cast pistons. Oringed the block and used 625+studs in SoCal stg2 heads and the new 9200AF SoCal cam! I'm running Exergy 250%inj and 14mmCp3. So to break it in and try to get it sealed up before throwing my triple setup back on it and going full potato I decided to throw a stock LMM core turbo on it and let it eat. Then I decided I should set it up with a dsp5 and then change turbos to show you guys what the differences are and what it actually does for you. So with the stock LMM turbo it did the following-

Tune1 435Hp 781ftlbs 25psi boost 1300degrees max
945us 14degrees
Tune2 495Hp 941Ftlbs 29psi boost 1500degrees Max
1130us 16degrees
Tune3 520hp 1033ftlbs 31psi boost 1600degrees Max
1175us 17.5degrees
Tune4 550hp 1105ftlbs 33psi boost 1670degrees Max
1310us 19degrees
Tune5 450hp 850ftlbs 30psi boost 1400degrees Max Way over fueled!
1525us 20degrees

Next turbo will be a 2.5Stg1 I think or I may just jump to my stg2 and I will just go up through my turbo line up and post the results as I do it over the next week or so. I will leave the fueling alone and only change the vane tuning when needed. I have a set load file for the dyno which is a 1800rpm to 3700rpm sweep over 15 seconds so it is good and loaded the entire time. Here is the video from tune 3 from outside. I will also post a picture of the dyno sheet with the runs on it. Hope you guys enjoy this. Stay tuned!

550hp on a engine dyno is there some sort of corection in that? I though without driveline loss it would max out over 600.
