Trade secret im afraid Bruce. you need to be above 200 posts

It was a recommendation from a diesel tunner cant remember all the ins and outs now to be honest.
If you review my previous posts I think its still there.
On bosch pumps there is an orange connector. Remove the orange connector.
There is 3 pistons in this pump but only 2 get used the 3rd one kicks in higher throught the rev range. Removing the plug makes the pump run on 3 pistons. This increases lower down power so you dont so much of a surge of power. Making the turbo a lot smoother and very little lag. My turbo runs from 1500 rpm all the way to 4000rpm
I think your car needs to be re mapped and a 110 hdi also.
Rappy
. For me get a remap followed by uprated clutch and flywheel. In the words of my mate V6 grunt with economy. No lag. Just a kick up the backside If you decide to boot it. Also remove the connector from the fuel pump. Which increases the boost of power low down.
