Don't mince around!!!!!!!!! I did for ages and kept weighing each different tuner against others, and ended up just totally confused
But finally at GTI international cos Revo had a fab hot babe promoting their products, I went for stage one with switch thingy - No regrets at all car is wonderful, can be an total animal or a complete lady. So close yer eyes throw a dart and just do it. They are all good, Mk5 is a tried and tested platform pretty much all issues long since worked out.
I ultimately chose my remap cos of the hot babe!
Go out and enjoy yer mota again, I do every day now!
HTH cheers
