which pump is the better pump over all non i/c or the i/c pump..
i have a 1993 and with the fuel screw at run away 6x18 injectors no afc with a stock turbo the truck doesnt smoke like my 91 dually did ...

6x18, no AFC and doesn't smoke enough? That's not natural.

Neither pump is "better." I believe Brian said the Non I/C pumps have slightly larger DV's, which might be good for a very slight increase in horsepower, like 10rwhp or so.

What are the specs of your truck. Fuel supply, turbo?

Part of the problem is the piston pump not keeping up with the 6x18's.
