The clue here is that the problem started after the repairs were made post-crash. It sounds awfully like some of the turbocharger's plumbing has been damaged/gone missing after the crash. If so – and it only takes a minute crack in the piping – the engine can lose turbo-boost, which will produce the precise symptoms you've noted.
While the turbocharger itself will be working fine, the boost it produces is being allowed to escape into the atmosphere instead of being pumped into the engine to produce more power. That's why it sounds noisy, and also why it's not delivering the performance you're expecting.
The explosion is a result of the air/LPG mixture in the intake manifold igniting, most likely set off by a stray spark. Change the plugs and plug leads again, they are usually the cause of this problem.
OLDER systems generally use up to 30 per cent more LPG than petrol, whereas a new injection system uses a little less LPG, more like 20 per cent, so there would probably be a saving. A new injection system typically costs $4000-$4500. Is a switch justified?
