With my new EZ on setting #3 and stock injectors, where I would see the most smoke is as follows (HO & 6 speed):
Put the truck in 4th gear.
Run up to 1500 RPM.
Cruise at this speed until boost stabilizes (should be about zero).
Now, nail the throttle wide open.
At 3PSI, the EZ starts fueling - max smoke.
As the boost goes up, the smoke would trail off to a light haze and then disappear at 30 PSIG boost.
When towing our 5ver, I'd get a healthy puff at every shift when I got back on the throttle, then it would clear up as the boost came up in the next gear.
Moral of story - low boost & extra fuel = smoke.
My present concern - the smoke's gone, and so is (I think) the "poke".
