Marvel Speed magic Port??310whp S/5 Stock Turbo??
I Can't Believe it Myself ?? Jus got off the dyno with" Nightmare77" 
Iv'e Been Tunning Rotary's for awhile & still In Shock. Only Because Aj The owner
Has Your Basic mods Like 255 Walbro pump, 720 sec Inj, Haltech e11, No Front mount I/C No Meth INJ No Ign Amp, No upgraded lines etc...... I Even had Mike At noribilt reset the MUSTANG DYNO, Cuz I said "NO WAY" The Boost spiked to 10 psi & fell off to 6-8 psi after 6k rpm. It Takes a Tuner To Extract Power, But Props To DON MARVEL, For The "magic Port"
Pic's & Vids Commin Soon ...........

Something very wrong here...550/720cc injectors aren't enough for this power level at the rear wheels(more like 260whp) Neither is 7psi on a stock turbo.
Has this car been to the drag strip? What kind of numbers does it produce there?
Have it tested on another dyno before you believe the car is really making numbers like that.

but let's not be so close minded.... I ran 13.00's @ 106mph Like back in 1993
Factory turbo factory ecu, all i had was 550/680 cartech FMU cartech FMIC, and a msd Inline pump. And The car was daily driven
HAAHHAHAH, Not laughing at you, But didn't you read my 1st post?? I can't belive it myself??? but trust me I will be running this down a dragstrip, Only if the owner lets me but let's not be so close minded.... I ran 13.00's @ 106mph Like back

what looks weird is, usually the Hp and Tq curves cross around 5252rpms but yours shows them crossing at around 5550ish rpms i wonder if that has something to do with the odd reading

Crazy numbers. 550/720 is just barely enough fuel for that HP number. Maxing out the duty cycle but possible.
This "magic port" is what I am interested in. Somehow I doubt the details will be revealed.

I've been on mustang dynos that read really high before, I seen 700rwhp once( even after settings were double checked).. Didn't dare post that dyno, lol !

No, you just donīt understand
You can extrapolate torque or HP from any point of powerband and it will be correct.
In regards of numbers: well, fuel system operated at usual base pressure around 43.5 psi "could" support such power, but duty should be north of 80%. More logs, real world test!!!

The 2 most interesting aspects are:
A) Toque, even a med/large street port sees a rather significant drop in toque as a % of hp the more power one makes. Yet this magic port seems to fix that issue.
B) "Stock" turbo, it has been well documented that the stock turbo drops off sharply well before redline even on stock putted engines, yet this one seems to be just beginning a gradual decent north of 6800rpm.
