Have been running a chipit module for a couple of years, been great, noticeable power increase, especially when towing, along with better fuel economy. Until now. Towing 1.5tonne of caravan up long hills sends it into limp mode, to the point where I had to disconnect it on the weekend so I could get to the high country without stopping every ten minutes. From my research on here, I'm thinking it is an over boost issue when coupled with the 3" exhaust. I need some help Tony, I want my chip back
massive difference when towing these weights compared with stock!
