Guys There Is No Given Chart For Running This Set Up. You Will Need To Be On A Dyno Or Make Sure That You Have A Wide Band On Board And Monitor Your A/f. Use The Standard H.p. Jetting Chart That Your System Came With. For Example, If You Want A 100 Shot You Will Run What Ever The 100 Shot Pill Is For Your Kit, If You Want A 75 Shot Then You Will Run What Ever The Jet Size That Your Kit Calls For. Then Make Sure That You Use The Same Size Jet On The Fuel Side That You Just Used On The Nitrous Side. This Will Not Be Your Jetting Set Up. You Will Be Riiiiiiiiiiich. Go Run The Car And See How Rich You Actually Are. Now You Will Need To Start Going Down On The Fuel Side Until You Get The Right A/f. Make Sure That The Pressure Is Always The Same In Both Bottles While Testing. I Usually Run The Propane Up To 180psi(no More Then That) And The N20@1000 And That's It. I dont recommend running more then 150 shot with this set up. And You Can Make Checks Payable To...........lol. I hope this help.

But then again you could use the trial and error method for a conventional n2o kit, but why when the basic jetting has been worked out. propane like a conventional kit will have some variations in a/f, but I assure you that the jetting table I will post again is a safe starting point. the biggest disadvantage of propane is the fact the zooming in a desired a/f is very difficult and prob the main reason is has never caught on to much (normally runs a little rich as it can vary and you don't want to go lean). A certain size propane jet can be used for a wide range of hp levels, and thus the reason it's hard to dial in an exact a/f, so staying rich is best.
