Welcome to the forum, you have the revised Bluefin dont you ?
I think so from what I have gathered ....
The result in terms of the increase is spot on to their claims but my graph is noticeably better IMO low down than the one on their site for a DSG Ed 30 in terms of the gain in HP and particularly Torque.
The manual gearboxes seem to give much more of a kick as far as I can tell by looking at the graphs but the DSG is quite restricted in torque levels so is smoother and gains rapidly rather than slams you back in the seat.
My car produced 229 bhp as standard so was down on what some get - and they asked if it was on normal unleaded, which it isnt .... just 5K of gentle running about with only the occasional blast, so still some way to fully loosen up. From 229 to 295 bhp is as far as I am concerned a very good result. I was going for APR until the last minute and TBH I don't think that would have given me any more at the top end, maybe more of a kick low down but SC are only looking after their customers interests by protecting the DSG. They said they can get loads more torque but do specifically restrict it for the box.
I would post the graph so you could have a look at it but can't seem to upload it anywhere other than the S2000 forum where I am still a member (having had two of them over the last few years
). If you want to see it I can post a link (assuming thats allowed!)
