    I am not talking about the crappy 50p resistor thing...

    http://cgi.ebay.co.uk/VW-DIESEL-PERF...item3a515968b9

    I ask because my friend has bought this one I think, and he is going to install it in the coming days.

    Anyone have any experience of these? If his is a good one, I will be sure to buy one from ebay myself at under £100, much cheaper than a remap.

    Obviously it wont be as great as a remap, but as long as it does the job, doesn't damage the car in anyway, I think most people would be happy.

    +25-30% BHP/Torque? not buying that one bit. more power AND fuel economy? not buying that either. all that from plugging a little box in? not buying that one little bit.

    To be honest, big remap companies ALSO state that, that in itself is not a shock.

    I would check out a reputable tuning company and go through them. At least that way you'll have some knowledge that its a "proper job" and you'll have somewhere to come back to should things go wrong. For £100 I wouldnt buy that, there are too many unknowns buying off ebay.

    Its not beyond the possible at all. Figures are open to debate, but increasing power and fuel economy can be done with little black boxes. Whether or not that particular black box does all that it claims im not sure, but from a proper company you will usually see good results.

    What about if it is a top rated seller?

    Also are all plug in boxes connceted to the common rail pressure sensor in a diesel?

    If your friend gets one just do some before and after 30-70 in one gear times, 60-90 etc. If the times improve it works if they don't it doesn't.

    But do the runs in one gear so quick gear changes and wheel spin don't play a factor.

    Yeah that's true. I am pretty sure they will work, he won't even have to do that, just generally driving the car, he will be able to tell if it is that little bit more nippy. A 20-30 bhp improvement can easily be noticed, but im sure he will check each gear too.

    The only issue is if these chips will damage the car in anyway, like the turbo, because they are a cheaper chips than from a big company. That we will know from time only lol :p:

    If engines could give more HP and Torque, and more fuel economey doing so, they would have made that as standard to get their cars to sell more.

    I can almost certainly say that that chip will increse the cars performace by 2-3% (a few extra HP) while ruining your fuel economy.

    Get a proper remap. Mine went from 100BHP -> 143BHP.

    That was 3/4 months and about 10,000 miles ago and no problems

    Wow over 40% increase haha, I have emailed the guy on ebay because he said it has many different settings. I am wondering on max power on high settings say for a golf gt tdi.

    Currently I have no car, got rid of my petrol golf lol.

    Where did u get the remap done? It's weird because alot of people online recommend bluefin/superchips, and they are a very expensive despite being effectively a plug in box.

    I like the box because you can remove it when u want e.t.c

    And you are a professor? If so, instead of having to sit down and write out insults, you could have corrected me.

    Yeah sorry about that, it's just an annoying thing I hear so many times...

    No I do not know much about cars myself but regarding the remap, it is very possible to get those gains. Turbo diesel and petrol respond the best.

    Once again, sorry for insulting you.

    OEM do not tune their engines very high, they have a standard map for their engines. This map is supposed to work anywhere in the world, any temperature, any grade of fuel, harsh environments, etc etc

    As such, in the UK where we don't have a harsh environment, our fuel quality is VERY good and our temperatures are usually moderate and not extreme, a more tailored UK map will unleash power that the manufacturers could not afford to because in Africa a UK map just won't work.

    So it is distinctly possible to get huge power gains and economy from an engine if it is tailored to the UK market.

    So what you said was incorrect and that's why

    To be honest, I don't buy it for one bit that a engine had an extra 40BHP potential that the OEM decided to lock away. Perhaps you could gain 10BHP if what you guys above said is true... but anything above that seems like a load of bull to be honest.

    Even if, that means the fuel economy will be ruined... correct?

    No seriously, just type in diesel tuning, diesels are ridiculously under tuned from factory.

    It might also be an issue where the manufacturer offers an engine in several states of tune as standard, the old VAG 1.9TDI could be anything from 90-150bhp..

    So surely if VW had tuned up eg. the 110bhp TDI and sold it at a similar price, it would infringe on the sale of the 130 or 150bhp TDIs (which sell at a pretty heavy premium even now)?
