The "mongoose" is supposed to do far more than the cheap generic obd tester mentioned above. Wether it does or not, I don't know, I have no experience of that particular device, but have used jag factory diagnostic kit. The vag-com mentioned above is an extremely good tool for the VAG cars, but you need to know how measuring blocks work, and if you are looking at obd cheap stuff for a jag it's totally irrelevant. Bear in mind that if you buy one of the many hundreds of cheapo obd testers as mentioned, don't expect it to do anything more than look at a few very basic engine parameters, spew a few generic p-codes and switch off the engine light. They will not help you with any in depth vehicle tests...

Thank you

I don't want go for the mechanic, because they always let me get old car parts replaced. So I was wondering can I do some chip tuning to increase car horsepower. The VAG-COM you mentioned, is it a connect cable? I don't think it can do any resetting or tuning, so it is not helpful to me.

Totaly aggree with above.
The OBD scanner I mentioned aboved is just a scanner (engine light reset, sensor data etc). I only mentioned it as when I was looking, there were a LOT of cheap scanners from China and on Ebay and from what I read at the time, a lot of them were very poor (some people ended up with something that looked right, but after it not working found out that it was just a box with a couple of flashing LEDs and nothing else).

The one I got did everything I needed at the time (read engine codes and see sensor data, so I could find out what sensor was not working - turned out to be the engine coolant sensor. Meant I could change the sensor - better than unknown garage saying this or that was wrong and charging for replacement of half the sensors) so good enough for simple checks.

If you are wanting something that allows you to do engine mapping then that is something completely different - different chips inside the device and different pin configurations. Changing the mapping isnt something I have tried yet but then I am more familiar with changing fuelling by swapping carb jets and ignition advance with a spanner and a timing light. Engine tunings just not the same if you can do it from the passenger seat and your hands dont get dirty. LOL.

which online shop did you buy tools from??
