Why people fit one. The TD5 responds well to a chip. You get more torque low down, which is what you notice when pulling away loaded or climbing. It’s a common upgrade for trucks that tow, carry weight, or run bigger tyres, because the standard map runs out of puff and the chip fills that gap. You can usually feel the difference in the mid range more than at the top end.
The Dastek Unichip is different from a lot of cheap tuning boxes. It’s a proper piggyback unit that gets mapped on a rolling road for your specific vehicle. That means the results depend on who set it up, and on whether it was mapped for your setup. A chip mapped for a standard truck won’t give the same result on one with a bigger intercooler and a different exhaust.
A few things to check before you buy:
-
Confirm it’s for the TD5. These also come in versions for other engines, and they don’t swap.
-
Ask whether it comes with the wiring loom and connector. Without those it’s much less useful.
-
Ask about the map. Was it set up for a standard truck or a modified one?
-
Check the plug and pins for damage or corrosion.
-
Confirm which ECU it suits. TD5 ECUs changed over the years, and you need the right match.
-
Ask whether it’s been on a dyno and what figures it produced.
Fitting is mostly plug and play, but the mapping needs someone who knows what they’re doing. If it’s already mapped, great. If not, budget for a session on a rolling road.
One honest note. A chip alone won’t transform a tired engine. If your TD5 is down on power because of a boost leak, a clogged EGR or a worn turbo, fix that first. A chip on top of a fault just masks it.
You can buy this Unichip from landrovergenuinepart.com. Order online, or email us first if you want to confirm it suits your ECU before you purchase. We’d rather check the details up front than have you send it back later.
When you get in touch, tell us your model, year and any ECU details you have. That’s usually enough for us to confirm whether it’ll work.

“To keep my Range Rover P38 on the road I am having to order genuine spares as some parts are no longer available. This genuine hose kit arrived complete with top and bottom radiator hoses and clamps, all of which were OEM and correctly moulded. It was fitted without any problems and I’ve not had any coolant weep either. Genuine parts for older models are a godsend, this site knows what I need.”
