Best mod so far

Well I say , my 1999 td5 manual disco 2 has just got a lot lot better ( while I wait for dynachip ) removed that gigantic mid box and replaced the back box . Holy cow batman , she goes like stink and sounds fantastic , still quiet inside also superb

I was also very surprised at the gains from this mod. I was thinking that the car would just "sound" more powerful and that would be it.

Yours should already be cat-less, but an egr delete will also work well.

everymod so far has put a smile on my face , n this one tops them all , so far i`ve.........

removed egr
cleaned all them engine sensors
new air filter
replaced the turbo modulator thing on side of engine
a few turns on the turbo wastegate
removed the mid exhaust pipe
new discs n pads fitted
rust treatment n zinc spray and stone chip paint

and even setting the heater to econ helped

Remove EGR,
Remove back box,
New head,
New injectors,
High flow air filter,
High flow oil filter,
High flow fuel filter,
Clean intercooler, all pipes with parafin,

All have put the MPG over 30. So not to bad.
