Car starts and die
I just finished my setup with a chipped ecu but my car starts then die, i gap my sparkplugs at .28 to .30 but i dont know what its happening.
I get a bin for my setup at 12psi, but right now i only run 8psi. The sparkplugs are stock and smoked.
What can i do?
My setup:
Stock Z6
T3 A/R .60
8psi
DSM 450s
DSM intercooler
Stock fuel pump
Chipped ecu with uberdata
Open downpipe

Now i have 2 problems, the first are i have boost spikes, the boost gauge jumps to almost 20psi and my wastegate are set at 8psi, i connect the wastegate to the intake manifold. The second are my car bogs, im thinking about spark plugs but i gapped it at .028, maybe i need one step colder or i still have some boost leak.
Any help?

Re: Car starts and die
well if your getting boost spikes check your vacuum line to the wastegate actuator. for the usaul mistakes a bunch of stuff t'd off of the same line, or just a leak.
It could be a bad manifold design to if you have an external wastegate. like the rvhard manifold were the wastegate is on just one of the runners.

Re: Car starts and die
Ok, wasnt the wastegate, was the boost gauge. I put a boost gauge from a friend and it read solid 8psi 
.
Now the only problem left are that in first gear the car bogs untill boost, when boost hits the problem gone, that occur only in 1st gear, and i cant rev to more than 3k in any other gear the car pulls ok.
