The 2009 TDI ECU does not allow chipping or flashing. Diesel Power has a performance module for sale already. Its based on 2 years of European TDI Common Rail Jetta development. Is there a difference in PMs? Who has had a good experience with what? Joe at PD says his give 20%power increase and 10% economy with a 3 year warranty. That sounds good but for $650.00 is there a better one? Gotta know!

Don't know but I would wait for others to try it first. I think the diesel particulate filter in the exhaust is all new and the calibration of the engine is slightly different. Is the warranty for their box or does it cover any damage caused by their box. I haven't heard of a new chip but it's just a matter of time, which is why I would wait.

For a car under warranty, a removable box might be a better idea. A chip should be transparent but they aren't out yet, they aren't tested long term, and it's possible that the dealer could detect it. The new ECU is encrypted which just means that it'll take longer to get a program out there. BMW ECUS can detect if they've ever been chipped and if they detect a chipping, they flag your VIN number.

More info on tuning boxes

For common rail ie 2009 Jetta TDi, which has been out for two years in Europe, in similar form they tell me: DieselPowers box plugs in between the Rail and ECU. All it does is increase rail pressure which leads to superior atomization of fuel and increase of power about 20% and economy 10%. If you start looking European motorheads have been using these for years. The DSG limits overpowering and clutch slippage may occur for manual users.

Do it! Someone has to try it and shouldn't a tuning box come with some sort of warranty that it won't break your car?

Nice, we should start seeing some turbo upgrades in the future. With the 16V head, it should make for some better breathing.

This Engine is 170hp in Europe

A 20% increase in power,as was said is now 168hp.

I think all that this power box does is bring it up to European Specs,which is plenty!

Other than the tuning and mph/kilo and minor options, is there any other difference between the US and European Jetta? Why did it not just come like that?

I'm not sure about Euro specs but I think it's a different turbo as well. Their cars have used different tuning and fueling in the past. It didn't come that way because of US regulations and that's probably what they wanted it to make. If anything they could have used a less powerful car to get a little more fuel economy.
