ok so the rents got a bf dedicated lpg falcon and it has been working like a dream but lately the revs have been hanging a bit so he took it in to the ford dealership and they said the computer has s**t tis self and its going to cost $1200 to fix and i was thinking he could get a custom tune for that much.
so i was just wondering what everyones thoughts were.

i would just buy the ecu, but hunt around on ebay first

So I take it apart from that its running OK???

I would take it for another opinion 1st before parting with money....
and a second hand ECU could be found at a wreckers much cheaper than that I am sure
