Hm damn, I was hoping you have that problem with your stock one. For over two years my stock car will randomly bog through acceleration and I've replace wires, plugs, ignition coil, dizzy cap/rotor, fuel filter, etc...there's no "pattern" to it, just does it when it pleases while I accelerate and it's annoying as hell.

Maybe it's your map?

I would look at two things on the BIN:

1. Fuel supply - more fuel needed within the rpm range that it boggs
2. Ignition timimg

If you haven't tuned it yet, you should do so now.

My 2 cents.

Mine would bogg sometimes but higher up in the RPM. When I add more fuel the bogging stops but I get a little back fire (popping in the exhaust) when cruising which is the result of a little too much fuel.

You can remove some fuel and see what happens. If that does not solve the problem, add some fuel.
