when is it too much?
 

im running a 2gph (123ccm) pre turbo and 10gph (630ccm) post nozzles with a 150 psi pump on a 61trim t4 turbo.
at 15 psi im hitting bout low 10s high 9s sometimes. running a progressive kit. start at 5 psi and full by 10 psi.

using 720/1680cc injecors and get bout 70% duty cycles.

according to the calculators online i should be running 8gps, should i go with a smaller nozzle?
im planning on running up to 20 psi. and using 50/50 mixture by weight.
