"Missing" w/ JRSC & BBK

I have been having a problem with my JRSC and was wondering if anyone else had any ideas. While accelerating anything more than very lightly, I get missing between about 2500 to 3000 rpm or so. It worked fine for a while and then this popped up and I am at a loss. The plugs and wires only have 13k mi on them. I hooked up a vacuum pump and gauge to the diaphragm and it holds vacuum just fine, so it's not leaking. It holds 15in of vacuum at idle in the manifold. I don't have a boost gauge or a wideband, so I can't use those to test. Does anyone know if Jackson Racing does troubleshooting if I take it to them? Any help would be greatly appreciated. Thanks.

check the 02 sensor heater fuse (i think its number 18?) had that happen to me. Though it definitely sounds ignition related.

O.K., I'll have to try re-gaping and make sure to check the O2 heater fuse. I'll let you know how it goes. And thanks.

Unless you have a CEL don't bother checking the fuse. If it was blown you'd be throwing codes.
