Id sit on your money, ive had 2 standard GTi's and now the Edition 30.
Totally different in character and looks alot nicer imo. For me twice of having a normal MK5 GTi and now " No way in the world" parting with my Edition 30 says something.
If you remap a standard GTi and remap, it will perform simular to a standard ed30 ,but with the smaller turbo, will spool up quicker but will fade higher up the rpm.
Stage 1 Ed30 will get you to 270 approx, add another 10bhp for stage 2. and i can tell you now, the car handles the power with little fuss, and by eck, it flys, to the point of not much unless your in a supercar will leave you behind.
Awesome car and with dsg again gives you shifting advantage again punching cars with more horsepower.
Up to you, but id know what id do fella.
