Anyone know the best tuners here in WA for these Engines ? preferably in Bunbury, as at the moment the car in unlincesed, as it has to be trailored...

The engine was running fine, so we took it for an easy run around our test track, and it has developed a miss, and is very lean in burning fuel ( lots of black smoke behind the car)

Any Help please ?

Thanks
Pete

This is what the engine looks like (although mines red )
