Do Power Chips realy work for Common Rail Turbo Deisel Engines

Yes they are, in fact they can increase your power and torque by 30%, Tunit have an adjustable plug in unit, Unichip also have a good unit.

There are also places you can have your ECU re-mapped, these are normally the cheapest of the power upgrades and have more options to give more power.

Other options are, a larger intercooler, 3" mandrel bend exhaust, changing the centre muffler (do not remove, only replace) silicon intercooler hoses, the list goes on.

One of the best power upgrades is;

ECU remap or plug in unit
Bigger intercooler with Silicon hoses
3" exhaust with centre muffler upgrade

They sure do, but what is usually the case is you modify the motor in some way, like bigger intercooler and exhaut system, then add the chip, and it increases fuel and boost, to give you better performance. Be very careful, as there are chips and chips....major brands are safest bet.

I am thinking of a Steinbauer(?)....silverback

I fitted one from this crowd:

Their website says: 07 V8 Landcruiser single and twin turbo plug in tuners selling strong, approx 35kw & 130nm of extra stump pulling power $990. Dont pay more for lower quality tuners that dont get the results.

35kW is 23%. I got 12%. It was a waste of money. I took it off to see if I could tell the difference, nothing, ON or OFF. I discussed exhaust systems with the owner in Brisbane too and he said they were not necessary. His chip was all I needed.

There are some informative posts on LCOOL:

Just do a search. It seems to me that most of these devices inject more fuel and that's not what I wanted.

cheers

I thought about chipping my CRD but the research I did kept coming back to pouring more diesel into the engine to do it which = increased fuel consumption.
So I had a talk to a fellow I know who runs an exhaust business and he reckoned he could get me a 5 - 10% increase in power by playing around with the exhaust system.
The OEM exhaust is fairly well baffled and his view was that by opening up the exhaust he'd get the turbo coming in quicker, virtually eliminate any turbo lag and excessive back pressure which would be robbing the engine to some degree of power by using some of it to push gases through the restrictive OEM exhaust.
I decided to give it a go so we played around with 6 differently configured Mercury mufflers. I didn't know which one I was trying, he just gave them a number and I tested.
Surprisingly there was a difference in engine performance caused by the back pressure created by the angle the pipe went through the muffler.
Anyway I settled on the muffler that had around a 3 degree angle off straight. There wasn't any noticeable difference between dead straight but the 3 degree angle gave a deeper note.
I haven't had the engine dyno tested but there is definitely a noticeable increase in power and torque. I've also fitted a K&N Air Filter to get improved air flow.
Fuel consumption has reduced from 10.2l/100k at 100kph on average to 9.5 on average.
The jeep techs who service my vehicle agree that there has been improved performance from the engine of around 5%.
The exhaust guy reckons I've chipped the engine without "chipping" it.
Anyway for what it's worth thought I'd let you know.

Would suggest a Safari chip as its programable to each individual engine via a laptop software program

We have a DP chip fitted to our Hilux and the improvement is very noticable.

The Hilux weighs 2700Kgs and sitting on 110Kph we get about 10 to 11 L /100k.

With the Trak Shak on the back weighing 1400Kgs we get between 12.5 to 14 L/100k.

Yes they do work and are worth it.

It's not about speed but easy of driving, before torque came in around 2300rpm and stayed flat until 4200rpm now it comes in strong at 1400rpm and stays until 4500rpm.

Why not try a DP chip and if you don't like it take it back and get a refund (they offer it on there web site).

But a warning you will become addicted to it.

Ok niave question.
I have got the free software for the OBD2 compliant engine in the 2002 Jack and it would appear that you can do some reprogramming of the ECU for more power/ better economy. The catch is that I have yet to get the OBD2 to USB lead, if I could find the pinouts I could make one, my research continues. I would have thought though from a purely high school physics stand point that if you want more out you have to put more in and I'm sckeptical that you can get say 30% extra for no extra fuel burned but then most vehicles would be factory preset to some manufacturers optimum so some tweaking may give you some advantage but the cost of these upgrade chips is I suspect exponentially larger than any realistic gain unless you want to throw more coal into the fire box.
