Kev: my personal objective is of 200bhp, i.e. 100 bhp per litre. This to me is the right figure, the standard engine will be fine. If a professional then re-mapped and boosted it to its full potential I'm confident it would kill a V6.
ALXege: If someone gave me the money to buy the Emerald ECU, I would merrily continue the project using my car and then install it onto their car all polished up a couple of months later... Realistically they would need to part with £1,200 in total, and I would not be making money, but at least I'd have seen it through!!
It is also a very loud mod... I have no idea how to make the damn thing quiet - I am thinking insulating foam inside the bumper. A re-designed interface plate will shut it up a bit, but that is like a couple hundred quid of welding and stainless steel.
