Boost issue

[Rhys033]

Currently on my fabia vrs se pd130 

 

GTD2263vz 

WZM injectors 

SACHs SRE 

4Bar MAP sensor 

n75 Mod 

 

I have an issue the car isn’t boosting well and the revs seem to jam at 4k when I put toe down then I have to let the revs come down to around 2.5k for the throttle to be responsive again. If I feather the throttle it will go all the way round. 
 

When I had 1756 the car was fine however I took gearbox off and it split two wires ( shown in image ) and currently connector blocked them could this be causing the open circuit? Car also dies quite quickly when left say a couple days. Check map sensor also I have swapped with a working one the wires look okay. 
 

I put the N75 on when was on 1756 turbo was fine I am yet to check the vac lines but again the car does boost just not hard at all and at like around 3k then jams at 4k. The car is on the same set up as my friends and currently same base map file.
