Citroen Relay 2000-2006 [2.8 HDi 128 bhp | ECU Remap | Chiptuning ]

The 2.8 5 Cylinder (Sofim) engine fitted to the PSA range and Motor homes is a very good base for tuning. Power output for this engine varies depending on the application and use. The 169bhp and 279lbft is suited to all vehicles including the 3.5t motor homes but where there aren't such weight restrictions the power can be increased further still. The torque increase is actually 73lbft as these engines only manage 205lbft standard, not the 221lbft that PSA claim, which makes for a vastly improved drive. We develop all of our software on the rolling road to ensure accuracy in terms of both power delivery and also to ensure fueling, boost pressures and exhaust gas temperatures are all within tolerance. Our aim is for maximum power whilst maintaining optimum reliability.
