Hey there,
I used to have a tdi tuning box for my 1.6tdi, switched it for a full ecu remap including releasing all torque limiters. I also already have a DTUK pedal box and recently purchased a DSG flash software remap from JFA automotive.
Wow, how can I describe it.. I must say the remap and DSG flash combined has completely transformed this car! I always wondered why before my car would feel fast some days and others it felt like my DSG wa holding me back.
As soon as I did the full remap and DSG map combined the car just effortlessly pulled like a train from low revs and just keeps going, it literally feels relentless for a 1.6 and the soundtrack is just as good, I can hear the turbo spooling non stop even in comfort mode!
The 0 60 with the tuning box was around 8.5 seconds, I timed it again and I I 7.6 7.8 and 7.3 but the way it launches really surprise me, there barely any lag!
I would assume you can't go wrong with revo but do consider giving TDI tuning a call, and also consider doing a DSG remap if you have the 7 speed auto, I wish I did the DSG remap before, as I felt I never got the full benefits from the tune.
In regards to tuning box vs full remap, even though I loved the difference with the box in, the remap combined with the DSG map is just in a different league altogether!
