These 25bhp mod chips on ebay....

has anyone tried them and are they any good? 25bhp seems a bit far fetched just by fooling the ecu into thinking the engine is taking in cold air, but does it make a notable difference at all or should i save my money and get a more expensive remap instead?

I think you know the answer without having to ask....

yeah very true.... just throwing it out there

they are a pile of sh!te not worth the ebay list price. it does change the power curve and give a few flat spots too

My frind had one on his Passat - I laughed for a long while when he showed me it )

Youd be better off with no air filter.

Remap..

I thank you.
