UPDATE: After speaking with the guys at TDI tuning they said it was okay to fit straight away, they have had plenty of Transit Custom owners who have fitted brand new.
First off I started it on map 4 which is the economy setting, there was a minor improvement in performance but nothing too significant. However after running this setting for 20-30 miles as they suggested I then changed the map up to map 6.
This has definitely made a BIG improvement in performance. It now pulls so much harder!
The surge in 2nd 3rd and 4th is awesome!
I was very skeptical about fitting this, but I can honestly say It's a big improvement in performance. Wether or not fuel economy has improved I'm not sure, I'm not so worried about that anyway. Had no issues with the van at all. Fitting was easy! The box however is a tad on the expensive side (£419.99)
I think as the engine starts to loosen up more and more it should get better and better, I think sometimes with these things it can be like a placebo effect where you get into your head that it feels quicker when it actually isn't but I definitely noticed a big difference.
I've had the father in law drive it aswell as he drove the van before it was fitted and he also couldn't believe the difference.
Take it as you will. I know there's a big debate about the tuning box vs remap, I just thought I would share my experience.
