Chip My Diesel
DIY plug in chip - $549
Claimed gains on WK2 CRD: BHP 21% Torque 21% Fuel economy 15%
The factors are 'as quoted' in each supplier's ad.
I did notice that DTA spends a lot of time talking down the chip option in favour of their 'superior' flash tune. I guess they have to justify double the price and needing your car at the shop for a day. I'm more interested in what really works rather than price, but also don't want to flush money down the toilet.
Has anyone done either of these mods on the CRD 3.0? Any comparisons and/or actual improvements you've experienced would be really useful to know. Any comments appreciated - many thanks!

I don't have either but things to take note of...
Cheap chips just up the fuel rail pressure in general and can provide the performance gain as it's very easy to get more out of a diesel.
Higher quality chips monitor and manage better and can include specific dyno tunes at extra cost. About $2000 plus tunes.
Exhaust gas temperatures can go very high very quickly so a temperature probe is recommended. Then of course you can think about Dawes valves and limiting boost pressures.
It's rarely as simple as plug and play. That said there will be plenty of people with no issues from inexpensive chips others who do get issues.
Ecu tunes can also be either generic or tailored to your vehicle via dyno tunes.
Either way do your research and choose the best for you.
