Alright, my car has been on LPG for aaages, and I can't complain (350km / tank - 68*.30 to fill a tank.. $20 so 17.5KM / $ Versus Petrol, 550km / tank - 68 * 90?? is ~$60 so about 9KM / $.. just shy of half the cost to travel), except that I found out a while ago (ok, something like 2 years ago) that the LPG leans out around 3500rpm or lower, leading to heaps of lost power (at least 10rwkW) + valves turning very white after a while (I guess this is cause they start to burn a bit when I keep the revvs up too long)...
Anyway, here are my options:
Buy an Elko EP175 unit to replace my current EP100... $220
Buy the EP175 + get it fitted & dyno tuned - $350
Buy one of these Impco setups and replace my current setup with it.. $??
Keep in mind that I want to make as few changes to the system as possible, including, if possible, keeping the simple ring mixer that I already have..
Any ideas on what to do and why?

No, its definitely leaning out because of a too-small converter.. For a start, the converter is only really rated to 120kW, and it would be producing closer to 150-160kW, and for another thing, the only adjustment on the converter is an idle screw and the mixer is a simple mixer with no adjustments at all (very simple system really.. I assume the little computer it uses does all the other mixture alterations)

i use the OMVL range of convertors, one size fits all, they retail less than $180 and can flow enough gas for a warm 351C .. I have the flow manually set at about 1/3 of max for my 4.0l
Pretty sure it's electronic.. when it was backfiring a lot a while ago (cause it kept leaning out), the guy tried to use a valve (econovalve I think he called it) but it was still way too lean, so eventually we put a new gas ECU in (not cheap :()

take the valve out all together and see if that lets moer gas flow.. Then if it runs better up high get a manual screw type power valve ( less than $10)
Ok, firstly I don't know where this valve might be, and secondly, I can only really tell that it runs lean if I run it on a dyno, and sadly I don't have one of them at my house :( (how cool would that be though )

i had an OMVL on my ea, my brother has one on his EB. ive seen heaps of cars with them. EFFalcon for one. they go well, are cheap, and you shouldnt have any problems with it.
youll be able to pick one up from a wrecker for under $100, and have it fitted/dyno'd at any LPG certified mechanic with a chassis dyno.
