My speedo/odo was also out by about 10%. 60kph gps~54kph indicated - 80/~71 - 100/~90. You will also need to add 10% to the odometer when calculating fuel consumption. (They will also add a bit to your fuel consumption as the car needs to work harder to turn them - especially around town.)

As to, "Is it worth it?" My vote is yes. With a 50mm lift and 265/75R16 you gain about 75mm of clearance.

Thanks Waz that was exactly what I was wondering, I think I'll just leave them as standard size, LOL I cant get into trouble that way can I?
Forgive my ignorance as I'm new here but Tombie is he on here? and if you dont mind me asking how much was it to have done and how much extra oooomph did it give. PM me if you would prefer.
Thanks to all it is appreciated

Tombie2 is his user name. He does 'chips' and there are a couple of threads in the D2 section on 'chips'.

What Stuuu said.

This is Tombie's website. All the details are here under Td5 upgrades. You will need to see if you have NNN or MSB ecu to determine whether you will need a new chip or just a remap. IMHO this is one of the best value mods around.

In terms of real word performance difference, I really noticed it climbing our range. I used to hold the throttle constant the range used to slow me to meet the speed limits. Now I need to back off to meet the limits.

I don't know if this is a must-do but I now tend to drive thinking about exhaust gas temps. On long hills I will go down a gear and use less throttle rather than a higher gear with the boot on the floor.

Thanks for the info Stuu & Waz I reckon I'll look at getting that done to.
Cheers Steve

I have had my ECU upgraded by someone else and also put in a larger intercooler.

The extra ooomph is quite marked for both the chip upgrade I did first and then the intercooler.

I mainly did it for towing the camper trailer so that I had something in reserve for 'Mum and the kids'. We have not changed our driving stlye and so the improvements/upgrades have really been so that we are not working the vehicle as hard to do what we want it to do if that makes sense.

Fuel economy is about the same or slightly better than standard configuration. Hope that is useful info for you.

It is Stuu thanks. I will be towing a mid 80's full height van which is suseptical (Spelling) to wind drag a bit so any extra would be great.

Our tdi Defender was working to pull or 1 ton (when loaded) camper. The stock standard Td5 was a book figure 25% power improvement.

In many ways that was enough but by chipping and adding the intercooler I have increased that by probably around 30-40% again. That gives me some in reserve so I am not pushing it hard to drive in a sensible manner with the trailer on but at the same time not dawdle.

Mine had only done highway driving with no towing for 127,000kms when I added the chip so I know it had not been given a hard life.

I'm definately getting keen on this upgrade as it would'nt hurt (I think) to have more under foot if needed. Thanks Stuuu
