Just thought I'd throw in my views of this product.
I had my car in the shop yesterday to replace a worn CV joint . When I say worn, I mean it was bone dry and needed to be cut out! Weird thing is the CV boot wasn't split so who knows where the grease went?
Anyway, whilst it was in I asked them to fit a new Rev G DV as the car has done 97k and thought it was a good preventative measure as I was struggling to get 30 mpg on a 'sensible' run, although is still pulled really well when I drove it hard.
Turns out the car already had a GFB DV+ fitted, but after reading this post I asked them to swap it out anyway so that I could compare and I could easily drop the GFB back in if I needed to.
Anyway, even though it's only been a day here are my initial thoughts.
I took it on a 'sensible run' with the kids through A & B roads and clocked up 38 mpg average, way more than I was getting on a long-distance cruise! This is a huge difference
I know that better fuel economy isn't everyone's idea of an improvement, and let's be honest I wouldn't have a GTi if I was that bothered about it, but when you do quite a few miles it's nice to know you can get reasonable mpg when you want to. The car also seems to start slightly quicker, has smoother idle and even appears slightly quieter although this could all just be my perception.
The throttle response does seems a little slower, but not by much and when I floor it it seems to pull just as well up through the revs.
I know it's early days but all in all, I prefer the way the car drives with the Rev G fitted but will give it a few weeks of driving before I give my final verdict.
Hope this helps some of the guys who are undecided which DV to fit.
