It sounds like you're either running too rich in open loop and require a custom tune

--or--

Your ignition system is not up to snuff

Is the engine EFI or carb? If EFI, what size injectors and MAF? Is the MAF an aftermarket unit that is matched to the injector size?

The MAF's will generally have the manufacturer's name cast into the housing for aftermarket MAF's. Pro-M or Mass air systems will mark the MAF sensor housing with an ID. C&L will use a different size sample tube to feed air to the MAF sensor element.
