Ok...I am having some problems...
My SS is stumbling under boost...and from what I can tell, from an over-rich mixture. I will get up on boost (7psi max right now) and it will cut out a couple of times, as if the fuel cut is hitting, but I don't think that the cut would be happening at 5-7psi. The car does have a rising rate fuel pressure regulator, and I was wondering if that might be raising the fuel pressure too much. Also for general background info:
New O2 sensor, New Coolant temp sensor, Premium Fuel, AWIC, Walbro Pump, Updated Hall Sensor, Stock Injectors
Any help is appreciated!! Thanks a lot guys (and gals)!!!
umm...help!

I don't think the fuel pressure riser is necessary at stock boost level. Even at 12psi i never had to modify fuel pressure on mine, and everything goes smoothly.

check you wiring, i had 1 bad wire near my pitching stoper and it gave me the same studdering under full throttel,(due to it grounding out when the engine torqued) i ended up replacing !everything! under the hood!!! then found the wiring by accident. I was at my wits end.
