Maps : Driver wish(late values),Torque limiter, smoke limiter,Duration 00 01 02 03 04, Boost, Boost limiter, EGR
SOI. N75 Stock for now

Extend boost column from 50 to 60 and tune last 2 columns for better pressure regularization. for n75 just log log, but youll have spikes for sure.

Thanks !

Other things u think are fine ?

Yep, smoke map fine, AFR good, torque is tuned nice also, in theory with these settings you have 370 380 NM and 165 170 hp.
That's the only thing that you can fix, pressure to tune it last 2-3 columns but with extension to 45 to 55 and 50 to 60 and also pressure limiter, dont tune it above 800 Pah atmoshpefic pressure, it's risky for turbo to have big pressure if you go in a zone with lower barometric pressure and turbo wants to spit more boost.

Hello !
What do u think about Durations ?
No problem for Boost limit map, i dont drive above sea level ;)

Ill look at boost map ;)

Duations are extrapolated ok. Better way to check this is on dyno and looking at smoke. Try to look if you have black smoke..but in fact you should increase duration with the same percentage of increasing columns. lets say 50 to 65 = +13 15 %
Limit that pressure under 800 barometric pressure because if you go in mountain zones turbo will suffer of overspin:)
Also i wanst so concentrated which duration maps you modified, but there must be 4 or 6 duration maps from 0 degrees to 25 degrees. concentrate on map 1 2 and 3 (10 15 and 20 crank degrees)
