Strange engine behavior.

Et, est-ce que vous aimez manger les petites chiens. C'est bon!!

what about eating little dogs........

spark plugs (one range colder and gapped to .43)

miss/hesitate on full boost in the lower rpm range (3000-4500 rpm).

Whenever the engine misses a/f will goes way lean and then way rich for a quick millisecond and the car will buck. After that, it runs smooth and strong. Boost gauge will read a little over 14.7-15.5psi and then drop and then go back to ~14.7 psi. That's why I think this might be a fuel cut issue. However, when full boost hits at above 4500rpm, the engine runs strong, even though boost hits higher than 15psi!!

Any ideas?

Sounds like you're misfiring. Gap your plugs down to at least .032 or even smaller if you're running 15-16psi boost.

morgie: I like the panel. Are they lighted switches? The dial is probably a Pot/potentiometer.

ciper : they are lighted yes, but i only connected the light on the green ones, to know then they are "on" .. the yellow one, since it's always on , i didn't connect the light . (it light too bright and was annoying)

the knob is a 5k potentiometer yup
