MY car dies! help!

[Swifty1638]

Well, I checked..the fuel pump is definatly on (it's 190lhp, hardwired) and the injecotors( 550) are not clogged. I think it's a boost leak, cause the car KINDA sounds like it's venting, and It doesn't hold boost the way it should. I was wondering if perhaps the stock spring in the wastegate could do that? It's got the 34mm flapper, but no upgraded spring..where can I get an upgrade for that, and how hard is it to install? Could the dieing on my when the clutch is in, be due to a bad speed sensor? The spedometer seems to work fine, so I am jsut trying to rule out more issues. I am gonna find a spray bottle, and mix in some water with a little bit of soap to see what's going on..hopefully, I can find the issue. I also think the timing needs to be adjusted, and the idle re-set..speaking of idle, do i really need to ground the plugs, and then turn the biss screw, or can't i jsut turn the dang screw? That's what I've done, but what does the grounding of the fusebox, and plug behind the battery yield?
