Ok. So if it's a valid figure. 
Spose time will tell how long it is before it grenades itself. 
And whys it not up for arguement? Mapping outside of efficiency islands and overspeeding turbos, surely isn't good practice just to get pub numbers is it. ?? 
Tuning out of outside of efficiency islands? So thats every tuners stage 2 KKK map down the pan then??
It still sound like you need to do more reading in tuning engines/ VE timing ect..... lol
Running this turbo on stage2 mapped BAM with stock manifold would allow for 16-17deg advance in the midrange tops and produce egts 950deg+ FACT.
Now taking the biggest restiction out of the factor which causes this heat build up and beack pressure.... The car is running much less heat build up which = power gain, the turbo is running LESS n75 duty cycle to produce the power, the turbo running less boost..... and its running 22deg of timing advance at the top end with 0CF @12.4:1 which I have NEVER done or seen before on a k04 with large port head.
Last year I would have been the first to say 290+ from a k04 would never happend but the sence has moved on now and with the 80mm tips and Relentless manifold, dp and decat things have moved on heaps and bounds..... nothing to do with tuner or mapping skills,, its just the tuner has a bigger safer scope.
If you go on the face book page you will see all the video and logs...
Like I keep saying every time you try to knock me back... I would only be kidding myself giving wrong numbers, if members go to a rr day and get less bhp it would look bad on me wouldnt it?
But so far over the year all of my customers car have made bang on, more or 2-3bhp less on other tuners rolling roads.... Why would I shoot my reputation in down?
I know other tuners want to put my numbers down, by giving free rr sessions and power runs on there dynos....
