nice ef :p, suggestion, tint your rear lights, not to dark, but lightly, will look good :) especially since your car is a dark colour.
also read through it properly for once, if you want a xr6, simple, get diff ratio and gear ratio and your camshaft adjusted/changed (which isnt to much) .
i test drove a "fairlane TICKFORD EL", one of 106 in australia, had a v8, but a "adaptive shift" gearbox, f$#% it went hard! my god, nothing ive driven has gone as hard as that thing, and i have driven turbos to chargers.
i will find out what i can with the lpg system, your out of tuning thing, is probbbably because you change to petrol all the time. you have to remember, stock LPG system from the factory runs off the computer, yours doesnt, neither does mine.
when u tune for lpg, and go to petrol it changes, and goes all weird, and vice versa if you get me? only run petrol if thats the case, if not, you have a shit mechanice, lol!
you need to lower your car ! would look nice :)
but yeah, exact specs or future exact specs would be good to know for anyone else who is interested in a High Performance LPG Kit for their falcon.
LPG Has 110 RON* (compared to ULP's 92 RON / premium unleaded 96 RON). The right unit, the right tune, you'd be saving money and gettin your power :)
