Just out of interest Alex. I've remapped a few vehicles in my time, and the general rule of thumb for power increases with car engines is around 30% for turbo-diesels and 20% for turbocharged petrols (diesels can handle higher peak cylinder pressures than petrol engines). Your remap has boosted power output by almost 60% if the engine was at claimed 190bhp (assuming your T2 is a standard 120bhp). Engines running hot or losing coolent, blowing gaskets, leaking injectors and over-boosting are not unknown after remaps. To be honest, unless you have a dyno readout, you've no way of knowing what true power your engine is putting out.
Not all "remaps" are the same. Stock "maps" can be bought over the internet and flashed in by anyone with a laptop and the software. I'd be careful if I were you.
