so i went to fire the car up and i have to feather the throttle to keep it runnin and spews a bunch of blueish grey smoke the smells like raw fuel. car has 750cc injectors but in the neptune program says theyve been adjusted to stock flow. what can it be or where should i start i want to get this thing going

cars setup

b16 with presision 5252 turbo with 3" D\P
ram horn header
sk2 intake manifold with 7750cc inj
aem fuel rail and reg
255 lph fuel pump
neptune chipped ecu

 

That's funny, My build is a chipped P06 with a crome base map for my 660 injectors and it does the same thing. I don't have a wideband, and I'm guessing you don't either. But my only hope is that it's just running too rich and that when it gets to the shop to be tuned they will sort it out.......anyone else think otherwise?

 

any cel?
double check timing

 

Blueish-Gray - doesn't this mean oil? And smells like raw fuel? I'm not an expert at all, but doesn't this sound like oil getting passed the rings and running pig rich?

 

Try adjusting your overall fuel down by 15% and see what happens ..
