SR weird and unique problem w/my SR

so I did a turbo upgrade 3 weeks ago, I went full out basicly

heres my problem

over 5.5k RPM when under boost in excess of 5 psi it seems like theres a speed limiter but for a gear.. theres jsut no response to the gaz pedal and the boost completely dies within half a second, anything under is fine 15 psi @ 4.5k RPM no problem If I boost at 4 PSI, it will go to 6k RPM + on any gears( did not try 1 and 2 too risky)

rev limiter is set to 7.2k RPM
speed limiter set at 180km

so the problem is not with the ECU, all the settings have been checked over by a proffessional, he has never seen this problem occur tried a few things to solve it nothing helped. it started to happen before with stock ECU and stock injectors

my question is: is there some sort of over boost protector or an internal rev limiter, anything of that kind I don't know

ya tune is fine everything ECU related is fine, it was my fault, my stupidity, i removed the wire inside the stock intake piping, because it got loose and was making a rattle noise , now the soft ruber intake got warm and the suction squeezed the intake shut letting no air in

thanks alot
