No graph or log of this? Its fast for that boost but come on people post some graphs and logs otherwise anyone can claim anything on here. If you don't want to that's fine but I really enjoy that sort of stuff and I'm sure many others would as well.

Tried a litlle more boost before 4500 to help the spool tonight, did 100-200 in 4.7' 2 persons in during the logs.
The long terms are still a bit low while all is ok with Lambdas and ignition angle stability, Todd will see that. (Btw, IDC is 60%)
The feeling is better, more torque.
I guess alone in the car by 1,6Bar and lower AT the car can touch/break the 4' at 100-200, I won't run massive boost.

As I thought you need special map sensors to read above 1.55bar !! Not sure if there are other Tuning softwares can see above 1.55bar maps !??
Congrats .. 4.7 sec with VTGs build is perfect

Right as well fast for that boost, the EVC showed 1,46Bar but the logs show more about 1,48-50Bar.
I will do dedicated runs when the tune ok and send the vbox file.

I run the stock ECU tuned by Protomotive, we are still in the boost level the oem sensor can read (1,55Bar maxi) for now.
Anyway the ECU does not control the boost anymore since the non vtg turbos,
the boost can be or not in the blind area of the sensor the ECU controls the same way the ignition and fueling.
Nevertheless I plan to bolt a GT2RS sensor or equivalent and recal the ECU to match with it, in order to be still able to check the boost curve mapped with the EVC6 even when 1,55 Bar are reached.
(I plan to run about 1,6Bar maxi, the goal is reliability not breaking records)

Hi All, many occupations took me not so close my car/built for more than 1 year, I'm glad it gets smoother now.
So after several tunes Todd told me "this last one is ok".
I didn't had much time yet to test the car but already (dramatically) killed a friend's F12 and ran a few Vbox times.
By 20°C AT did 4,2' and 7,7' at 100-200 and 250, one 96-209 showed 4,8'.
The boost is set at 1,55bar, just at the stock sensor blindness limit, the EVC6 shows peaks at 1,58Bar and IDC is about 65%.
The car is very fast and strong, I "guesstimate" power about 850 to 900hp.
I have vbox pics but I will retest with the card in order to send the result and perhap's calculate the power.
I won't raise the boost for now as I do not participate at events, only my pleasure, a few track days and a few friendly rolling "races" on desert clean roads. (Next is with a >1000hp GTR...)
Stay tuned!

Thank you Ali, no shifting from 100 to 200 (4rth) cause was datalogging, 100-250 is 4+5th gear, I will test if a gain with 3+4+5.
