DPCHIP

I fitted a DP Chip to my Prado 120, there was quite a noticeable improvement in performance, however, when I fitted a 3" exhaust the improvement was amazing!
It was like having an extra gear when towing our Vista RV Crossover.
I think to get the full benefit from the DP Chip you need to also look at the exhaust.

I didn't use a DP Chip in my HDT-FE but another "brand" to speak, I also have a 3" exhaust and dump pipe from the same people.
Difference with 3" when fitted was very good, with minimal difference to fuel consumption, power and torque were improved about 10% maybe.
Chip fitted about 6 month's later and difference was huge, power gain was so good that I opted to back it off 10% ( plug & play ) as fuel consumption rose as the right foot tended to get too heavy in metro area, now I find it spot on all round with fuel economy being a lot better and me not tending to bury my foot into it as much.
Power and torque difference after backing it off was hardly noticeable at all.

G'day Richard P
Just be aware that a DPCHIP and others like it, raises the rail pressure and therefore stresses the high pressure pump and injectors far more than when Standard, so it is reasonable to assume less life out of these expensive components. Instead of operating at around 20,000psi it will operate at or above 30,000psi. Not really designed to do that.
Other types of chip only modify injector action/time and don't cause the extra stress on the injection system components.

They all work to give more power/torque, it is your choice.

Thanks Guys,
I think I will investigate the 3" exhaust system and see what the cost is likely to be.

Thanks again for your comments

Richard P there are a few different chips for sale and a researcher did a comparison between the DPchip and another called chip it (I think). If you chipit versus dpchip The author describes some different test which may give you some good information.

You could have a go at this one - I have it in the Rodeo - Fuel is the same if you drive it easy - more fuel if you drive it hard.

But a lot more low down torque & noticeable performance, A lot cheaper.

Hi

I followed Tonyfish#58 and purchased a Chip for my Rodeo RA from CHIP EXPRESS.

It makes a huge difference in torque, power and smooth performance through the gears. Hard to gauge if fuel consumption has improved. Certainly no worse. Seriously I do have a problem keeping the vehicle below 100 kms as it wants to "fly".

My Chip came from England. 395 pounds plus 30 pounds postage...Aust $678 all up. Was at my door in 7 days.

Took some 20 minutes to fit with very easy to follow instructions.

I haven't bothered to change the exhaust at this stage.

In my opinion it was money well spent.
