N52B30AE Powe Up ?

[fjth7]

Hello Bimmers Guys..
i have a BMW E60 2008, Stock is 520i when i bought, but i was Swapped Engine from N46B20 154hp 200nm to Black Cover N52B30AE
i google it for this engine, someone say is a 528i not 530i, means this engine output is 230hp 271Nm
and now i want to Power Up, i google it again someone say you can power up this Engine like 530i N53, Power goes up to 268hp 315Nm
but you need to install 3 Stage Intake Manifold and Flash DME with BMW X5 E70 3.0si because this N52 from this car has a 268hp 315Nm
for installing this intake, no problem i will buy it, but how can i Flash DME with X5 3.0si, to Enable Disa Valve
i have Standard Tools, ISTA, wth D-Can Cable

and This is my Acceleration Car with no Passenger and No Spare Tyre from Boot, and 102mAh Battery, with 20L Fuel Tank

0-100km/h 8.0s
0-160km/h 20.5s
0-200km/h 32.5s
1/4 Mile 15.8s

just i need a Flash File from this car
and if you know something and advice about this please tell me..
i know about Bimmerlabs, they have a File, 325i & 328i to 330i, but probably just for E90 91 92 93, i don't know it is different for E60 or not !
Thanks Guys.
