Anyone have the instructions handy for adjusting/tuning the IRB Developments Dual/Two Channel Turbo Booster Box for Td5? I bought and fitted mine in around 2013 and seem to have misplaced the guidance since then (thankfully I haven't had a need to touch it). I'm currently have intermittent issues with the vehicle including surging and power cut off (suspected due to over boosting) so am trying to determine if the fault is the MAF or Turbo Booster Box is faulty or requiring adjustment.
Nanocom Evolution spat out the following when I read the codes yesterday (it's been a long time since I've pulled them):
Todays code read:
On the drive home today I pulled over while it was underpowered and disconnected the MAF sensor which instantly fixed it. Hence why I have narrowed it down to either the MAF or Booster Box.
