I bought a Bluefin from Demon Tweeks and received a free K&N filter worth about £80, you need access to a laptop and the internet to download your data to Bluefin and they return the updated files to be plugged into the OBD port. It’s quit straightforward and the easiest method to remove if the van is still under warranty. The increase in performance is impressive but that’s not what I was looking for, I wanted an increase in low end torque,the guys at Bluefin were very helpful and suggested that I need to keep the revs above 1500RPM all the time to get the best performance and suggested that it was not for me and that I should return it for a refund (within 2 weeks of purchase) Demon Tweeks were very good and agreed a refund and even allowed me to keep the free K&N filter, excellent service.
I then bought a box from Bluespark, they were very helpful, the installation involves removing the air filter and the boost pipe with 2 very awkward 10mm headed bolts in a confined space to be able to lift up a rubber “blanket” that covers the fuel rail sensor, then attach the rest of the 2 channel harness to the boost sensor. Re attaching the 2 1mm bolts is a pig of a job and I was always concerned at how long the harness would take to remove by the roadside if I broke down and was recovered by Ford Assist. Again the increase in performance is phenomenal if you want to be a boy racer, but it didn’t give me the low end torque that I wanted. Bluespark were great and refunded me with no quibble.
Finally I bought a used CRTD4 unit from TDI Tuning on EBay paid £100 for it and about another £160 to have it reprogrammed with a 3 channel harness, any CRTD4 unit will do, it doesn’t matter what vehicle it comes off, they just reprogramm it and supply a new 3 channel harness, fitting is very similar and difficult as the Bluespark but by now I can do it in about 20 minutes with just 7,8&10mm socket.
The TDI Tuning Box is everything I wanted, great low end torque, increased fuel economy (its too soon to say how much) I can take roundabouts in third, coast comfortably at 30mph in fourth, cruise at 1725RPM in sixth at 66mph by the sat nav or 69mph by the speedo, I’m really pleased, oh and there’s still phenomenal performance above 1500RPM if you want it.
The van is a joy to drive and I would recommend the CRTD4.
