I totally agree with what Steve has said above, running a Stage 2 Bluefin'd Eddie in the best colour
I know that there are plenty of of other tuners out there that will get slightly more bang for your buck but I've been more than happy with Bluefin going from standard to Stage 1 and then Stage 1 to Stage 2 in the past 12 months. Definitely very noticeable power increase and mine feels pretty awesome as it is at the moment.
Having said all that and did I live closer, I would certainly give R-Tech a try from all the great feedback they get.
If I do end up going to Stage 2+ then I may jump off the Bluefin ship and over to a custom tuner like R-tech but as it is I'm a happy camper, plenty of power when needed and still decent mpg when taking it easy.
