TD5 power upgrades

Exactly. I had a certain retailer from a certain plug in box company state he could fit one to a 300 tdi.
You have to be careful, I also think theres a lot of over stated power gains from some chipping+plug in box suppliers.
You have to research your supplier before going deciding on your choice.
I can count on 1 hand the suppliers I'd go with for an ECU remap.

The end.
Do you have a dastek plug box in Jake? You mentioned a plug in chip?
And if I may quote a highly respectable tuning company's website regarding plug in boxes
"I have seen DIY fit plug in tuning boxes elsewhere... Do you sell these?
Absolutely not! The safest way to tune an engine's ecu, is to modify the software within the management system. By doing this, you can be sure that for every engine running condition, there is a safe setting that is governed by the map data stored within the engines ecu.
External plug in tuning devices fool the engine management into thinking it's injecting a pre-determined amount of fuel, when really the tuning box is increasing the injector opening time, just to put more fuel in, regardless of what is happening with the rest of the engine.
The most common plug in tuning devices simply plug into your engine's fuel rail pressure sensor, and add a greater resistance to the supply voltage. This fools the ecu into thinking there is low fuel pressure, so the ecu then increases fuel pressure to the rail to compensate.
This overpressurising of the fuel rail will allow more fuel to enter the engine when the injector opens, hence making more power. A crude method of tuning to say the least, but one that is so common! "

since its a sunday & my 90 is in bits i shall copy & paste a reply regarding the dastek powerplug from another forum that i wrote,
"We have already carried out many conversions on the X-trail with no problems, but as we have just updated our electronics hardware for things such as closed loop feedback EGT (exhaust gas temperature) & switchable maps for different terrains, we require all of these cars again to enable for us to develop the extra strategies.
We have an extensive OEM & works motorsport background, where we have worked with companies such as Mitsubishi (official dealer L200 upgrade) Isuzu (official Greek D-max upgrade) Ford motorsport (various prototype projects) De Tomaso (Guarà2000) Toyota motorsport (GpN Rally cars) the list goes on. As such we have the skills & knowledge to develop products that allow the greatest improvement in power, torque, economy & driveability, whilst still retaining manufacturer reliability & safety. This is often the reason we are chosen to partner manufactures & our products are offered through the official dealer network (often re-badged) whilst still retaining the manufacturer’s warranty.
Many of the members are probably correct in that majority of the products out there do not offer any gain & often cause problems, this is because the electronic principles employed are very crude & basic & do not work in conjunction with the standard ECU. An issue we face is that whilst those companies are not technically strong, they are very good at marketing, we of course are the other way about, but then our strength is in supplying other tuning companies & large volume manufactures.
If you look at our product range, you will see that we only cover about 35 vehicles as opposed to the hundreds covered by our competitors, but with the amount of time we spend in R&D on each new model, it would be impossible to develop as many products as our competitors, & given that we have all the equipment in house such as CNC pick & place surface mount board manufacturing, optical recognition quality control, wave soldering, in house chassis dynamometers, software/hardware design & manufacture, it makes one wonder how well developed other products are? Another problem we come across is that our results are never as good as what other companies claim they get out of their product, 99% of the time we are better than our competitors despite their claims (as tested back to back on an independent dyno) the remaining 1%, well lets just say I wouldn’t be prepared to run such high EGT’s – a by product of too much fuel and/or the wrong point of injection in my vehicle let alone a customers.
Some of the things that make our product unique are:
Referenced to engine speed (others will make you believe that they have RPM input 99% of units do not)
Referenced to true engine load (others will make you believe that they have load input 99% of units do not)
Referenced to driver demand (Throttle position, again 99% of units do not)
Referenced to engine temperature (in the event of an overheat condition our product will reduce engine output as a safeguard – no other unit has this)
Proper closed loop 3D boost control tables (not a boost increase due to extra fuel being burned as happens with all other units – no other unit has this)
Ability to alter point of injection (the crank angle at which fuel is injected is critical to reducing, fuel consumption, combustion temperature, EGT, soot content & noise – no other unit has this)
Switchable maps for altering torque delivery curve suitable for specific terrains (bluetooth enabled, not some dip switch that changes the overall output – no other unit has this)
True ECU OEM connectors, no scotch locks or soldering, easily removed & a tangible product for re-sale, if you ever change vehicle.
Propane enrichment control
Closed loop EGT control, allowing maximum safe power under any & all load/time conditions
Also our unit is the only product on the market (as far as we are aware) which is legal for use on the public highway, it has an E-mark (look on your healights you will see the symbol) & has passed all EMC testing for automotive applications, this must not be confused with TUV approval, which does not render it legal for use on the public highway in Europe.
Whilst I can’t promise you biscuits I can offer you tea & coffee, & whilst we really require a vehicle for 2 days testing, I would more than welcome you to visit our premises & have a look around & see the type of things we do. "
now, what i would like to see is an ecu reflash that can take an EGT input,also an ecu reflash that allows alternative maps that are driver changable to suit conditions & also what you are doing....
Can a reflash do the above? :roll:

Also whilst im here there is only 5 people on your list that do reflashes,not 6
that is if what porny told me is correct?
cos you cant count the same person twice :wink:

No I dont.
I dont have a Td5 engine either
I used a Dastek in our works Td5 Disco 2 after the Donnington show.
Drove up without it, drove back with it fitted.
I noticed a nice power difference.
We sell the Dastek product at work (Devon 4x4)
I'll be honest, i dont know to much about chips and tuning at the moment.
Beast5680 asked the question about power upgrades, i threw in my 2 cents worth (having had first hand experience now)
That was all.

Ive got no problem Jake. I bought a grands worth of O/D from you last year so I have nothing against you or Devon 8)
