even though the cat does bugger all on a car running LPG. Gas is certainly not to the answer to EPA issues, anyone thats called the EPA or an engineer will tell them this.

tuned my car today. Car seems to be making some decent power (enough to demolish the 2800 stall dominator :/) so cant report back on any dyno figures or alike yet, but will be at the track soon. specs : 440cfm throttle body twin b2 converters twin big lock offs single gas line t pieced in the engine bay run of the mill unmodified sprint gas tank decent highflow (t3/t4 with 0.50 comp cover, e trim wheel) not sure of the jet size in the idle hose, but have a 2.2 jet in the progression hose.. probably still a tiny bit rich at cruise, but a lot better than before. Have an unmodified 48 main metering rod in it also. Mixtures under full load (running 17psi) are 0.78-0.80 so a bit rich still, want to get it down around 0.83-0.84, but didnt have a leaner metering rod. Timing is around 16 deg advance at fullboost with a microtech ecu. the gas research stuff is very easy to tune also! I did it myself with a mate and his mixture meter in a matter of about 30 mins.
