You're welcome... I'm stretching a bit on the fuel dump, as it's not very likely... Using a thermo gun (can be sourced from longacre, they're pretty cheap and useful for all sorts of things) you can shoot each header runner and see if one of them is considerably cooler than the other. That would tell you if you're getting an incomplete burn in a particular jug. That's not the most likely, but possible...
The other is to make sure your MAF is clean. If running an after-mkt filter, the oils can dirty the MAF a bit. Some MAF cleaning spray could be helpful here.
Check/replace your 02 sensor as well (how many miles are on your car? Ever run leaded race gas? If answers are low and no, then 02 likely not a problem)...
A new belt won't ensure that it's not slipping... see if there's enough room in the tensioner to put on a .5" smaller belt, if so give it a try. You may have some slipping. If none of those things cure your problem, you've likely got a tuning issue...
Best,
Phil

The plugs are new & should be fine, but I'll look at them again.
I'm not aware of any misfires. If so, wouldn't that throw a CEL?
The alt bracket has been changed & the belt is tight (so I do not think it's slipping).
What would cause the dumping of fuel into the exhaust?
I'll shoot a message to Tony at PES.
Thanks Again!
