Nitrous jet size I have the Nitrous Works 175 shot plate system. I have noticed that their carb plates support 300 horsepower so I was kinda wanting to play with bigger jetting to see if I can net a gain (since more jets would be inexpensive). Anyone have a formula to calculate needed jet size or know off hand which size jets are for which levels? Obviously my calibration card only goes to 175. Need nitrous and fuel jet sizes.

OK found some jet calculators but I am thoroughly confused. My calibration card has a .076" jet for nitrous and .046" fuel for 175 hp shot. The calculator accurately calculates the fuel jet size for that size nitrous jet but it says this combo makes 260 hp. What gives????????????? 
I can account that this combo makes 175 because I dynoed ~130 rwhp gain with it (20% drivetrain loss).
