Hin Stu,
The pump is indeed mechanical and Andy quote sums it up nicely pal.

Category 1: Mechanical TDi
This engine can achieve good results, typically up to 30 BHP and 30% more torque, however, due to the mechanical pump not being controlled to very close tolerances when initially accelerating, some smoke may have to be tolerated while the turbo is producing initial boost. A free flow air filter will help this problem a lot.

On this type of system we can modify the diesel pump timing and fuel delivery along with an increase in boost pressure to match the extra fuel. This will give much improved throttle response and mid range torque.


Peugeot 306 D Turbo (intercooled)
This vehicle gains approximately 25 Bhp and 31 Ftlb of torque, giving this great little car hot hatch performance.

Its also worth noting that these improvements are on a vehicle giving perfect factory power already. If your vehicle is out of tune and down on power, you will gain more power than stated.

The cost of this work is £250 inc vat.

It takes approx 4hrs to do mate.
