If you consider the TMC, consider one of these instead to save you a LOT of money:
they do exact the same job, for a LOT less (cheating the ECU into believing theres lower pressure in the common-rail than there actually is, hence ordering the high pressure pump to increase preassure above normal level, thereby increasing amount of fuel that gets injected)...
The Novitec is a bit more refined, due to it also "cheats" with the turbo-pressure.
If you turn these common-rail boxes to the max. Youll feel when the box kicks in..Fun for a start, but bit annoying in the long run...Dont believe in improved economy...Oh yeah, the computer will tell you its saving fuel, but thats due to the ECU getting cheated by the higher-than-felt pressure, so it doesnt know the right amount of fuel getting injected. Rim to rim measurements will prove this statement :-)
I´f driven >300.000 Km with these types of boxes during the last 12 years & still do on my 2.4, so although i might sound a bit negative, its just to clarify that its not "pure magic" and not just win-win...A descent ECU-flash with car on rolling road will be more driveable, but for 60£ everytime i get a new car I´m still happy with the cons & saved me 3000£ if all the cars should have had the ECU-treatment instead :-)
If you want to do a rough measurement of before/after (You will have NO doubt about when box is installed), you can get a cheap OBD-bluetooth dongle ex:http://www.ebay.co.uk/itm/USB-Blueto...item486424cd56
Then install "Torque" from android market on any android-device with bluetooth...It wil measure 0-60 Mph / 0-100 Km/h and so on, including testing/resetting of ECU-related errorcodes...And believe it will do this on the free version too :-) Calculated kW & Torque i´f never had any useful luck with getting reliable within cars what-should-be figures.
Best of luck :-)
