i just got my twin turbo FD but im having boosting problems when it hits 4 psi its starts breaking up and fuel dumping, ive done a couple of searches and think its as to do with spark issue or the wastegate of the twins isn't closing properly. Please someone give me advise and help...

The sequential system is worth keeping but a bit complicated. Even after several years of ownership I'm not sure I completely understand it.
FWIW, here's a list of rotary shops in your State....if it comes to that. Make sure they're familiar with the FD....
