sparkplugs? wires? sparkplug gap?
too much boost for the amount of fuel will cuase knock, witch will make the box retard time and can sound like a miss under boost...
at last years MACG grants car had what sounded like a miss under boost, wich ended up being too much boost...i turned the boost down a bit and the car ran great...12psi is all you need...
get it to run great at 12psi, then you can turn it up and play your way back to 16 or so..
think about it... all it is, is air/fuel, timing, and spark.
is the timing spot on? 12* BTDC if it is, move on...
is the spark spot on? NGK or DENSO plugs gaped at about .020 with a good set of plug wires and a good rotor button and cap? if it is, move on...
are all the injectors good??
is everything plugged up properly???
calculatous eliminatous my friend...
