406 hdi 90bhp performance chip

[406silverhdi]

Ive had my 406 for 2 years and it really has been great

i had to cambelt done about a year ago and the clutch done last week, i always said to myself once i had these two done i would consider a chip

the car is on 130k miles at the moment

I do around 800 a week, about 600 is motorways, these chips say they improve performance AND economy

The ones ive seen on ebay say they will increase my bhp to 115, i had a xantia that was 110bhp which i loved, so is it worth it?

Does it really improve the economy if driven sensibly or is this all just sales patter

Any links to reccomended ones, or is it all just a waste of time?

Most people seem to think re-map is much better than these gadgets, (that work by 'fooling' the ecu into increasing the fuel pressure). Have a look at this or try a search.
