Its probably excess fuel smoke from the plugs being fouled up etc.... Probably just gotta do the basics mate like a full service (plugs, filters etc) and check the O2 sensor and stuff.... For any basic mechanical just use a trusted mechanic, TRG loves his imports so maybe see him.... For any tuning etc you may need then i'd speak to Jez on the coast (we can give you contact details) but just a friendly word of advice, there is a shop up here that calls themselves a "performance workshop" but i would trust a wrecker before using them again (I cant say on a public forum who, but happy to steer you away from them since all the bad dealings i had)...
Our cruises will be during the day, so you should be fine, keep an eye on the local threads and flick the guys a wave if you see them!
