at a simple 5% throttle pedal push the boost increase very fast and very much and will broken the engine because the ecu not have time to cut the boost
That is completely false, it will absolutely not break YOUR engine on spool, it is IDENTICAL to having the n75 connected. During spool the n75 is at 95%
your peak boost will not be that big .. because after peak boost 95% dc is actually underboosting on your car.
unless it is your N75 that is bad. The only way to know is to run a quick pull with wg disconnected, or replace the N75, or run various fixed wgdc outputs as a test.
n75 at 95% it is inverse like wg disconnected.
sigh.
when n75 95% the preasure push the wg and the turbo deacrease preassure in inleat manihold.
no
when n75 is 0% pressure pushes the wg open. at 95% the n75 vents pressure AWAY from the WG.
