Big bucking.....turbo

first I couldn't get any positive pressure from the turbo I figured it was boost leaks so I bought some 2" flex hose and Voilla done!! (tired of grinding and rewelding) Still couldn't get any pressure.....I figured the CAT was holdin' me back(it was) disconnected at the cat and boom HIT BOOST bitch doesn't spool till 4000rpm though.

When I hit about 7-8psi the car jerks to one side (and the engine seems to die) so I let off the gas and it comes back so I get into it again(cause I'm pissed) and it jerks again real bad.

can someone please tell me why my @# car cuts out at about 7-8psi which is where my "Deltagate MK II" is set at approximately.

I just got my datalogging setup going Rx and Tx wires pwned me for a while.

Just did a little searching, which is what I should have done in the first place but I still have ??'s

what did you do to figure it out, I'm using a bin off of Xenocrons site, it was NG55 for a ZC with 450's I think 6 or 7 lbs of boost. the problem you had is exactly what I'm experiencing.
