FCD problems
 

I have a Racing Beat FCD. Just these past few weeks I've been having some problems with some sputtering/missing at around 9-10psi and I just noticed this evening that when it occurs, my factory boost guage is showing nearly +400 mmHg. I do believe that would cause fuel cut. But I have an FCD.

Bottom line, has anyone else had this sort of problem with thier FCD's?
