Hey guys i have an AUII on factory fitted LPG. I'm am hoping to get some guidance as to what i should mod next to increase power. Currently i have got full exhaust including pacies cat and lukey catback. The only other mod to date is a CAI. I was hoping someone could give me some ideas and possibly some places were i can some quotes. I was thinking along the lines of a new cam. Or even freeing up the factory LPG system in some way (maybe new TB). I'm obviously trying to keep costs down so im not looking turbo or supercharging. Any suggestions would be appreciated.

Not much you can do for it. It is poverty pack type gas, not built for power. Cam might help and shave the head and some port work. Probably too much money for the gain. Regards TPVM.

The stock TB (with integral mixer) is smaller then most of the aftermarket retro fit mixer rings.
Changing back to a regular TB and fitting an after market mixer of between 42-45mm will free the system up a little.
Note that changing mixer size with most defiantly effect the tune, it will cause a lean condition.

The AU factory gas system is not the modifiers friend.
