few questions on mine

[Jake]

all HDI's have a bosch fuel pump . .you're getting muddled with the Xud engines . . yes i reckon get rid of the chip, probs be shit and you'd be way better off with a re-map . .as far as the sluggishness goes . . .service her mate, oil and all filters and then see how she goes . .

hope this helps . .

Pretty sure mine had a Siemens pump when I owned my hdi.

Was a while ago though!

oh ok . . . . . . i'll pipe down then, don't think it makes a deal of difference though does it/ . .anyway are you sure? . . .thought they did ecu's and shit? .

Not sure at all! Haha, just remember seeing it saying Siemens around the fuel pump area!
