OK I did my vac. hose upgrade this weekend. Everything went well, did',t break any solenoids, did'nt mix up any connections. SO I put here back together. She started up, idle was normal, running smooth. Well here's the problem. In neutral I can rev it up to redline no problem, when driving if I'm easy on the gas, she's fine. If iI try and really get on it, she start's breaking up bad, like I'm hitting fuel cut off or the ignition system is breaking down. It seems to happen from 2500 to 3500. I did manage to get it going once or twice after the break up and my boost was a steady .8 / 1.0 / .8 bar.
Anyone have a damn clue what could have went wrong? I thought it was the old ground problem, I checked and I put the grounds back on the intake, I also added 2 ground straps after this problem occoured to no avail

 

Fixed the problem, the new fuel pump I put in last week crapped out
