Hi, I'm considering buying a Shogun Sport diesel version. However, having had a test drive, I found it quite noisy with lots of vibration at idle. When I mentioned this the dealer said there was a "power upgrade" available (basically an engine management system re-chip) which adds about 50-60hp but, he claims, also makes the engine much smoother and quieter. It costs 700GBP so needs careful thought before I commit. Does anyone have any experience of this upgrade? Is it really that effective? TIA...Mark
