That type of plate circulates nitrous and fuel around the entire body of the plate, and it has more orifices than a spray bar plate. Therefore, you need bigger jets than a spray bar system would require to keep the pressure right so delivery is consistent. Also, is it using their solenoids, and are they rated above 150hp?
I would think 110 octane is plenty for the main fuel system and nitrous system. A good way to see what is going on would be to read the plugs as mentioned. Very possible it is leaning out.
Yes, i bought the kit new, and the solenoids are rated up to 300. it came with the jets for a 50,100... so on up to 300. im putting the jets and setting the retard exactly as they say.
Fuel is set at 6 psi flowing like they want, everything... bottle is always around 950-1000 psi.
