I installed my ebay 'performance' chip yesterday... What can i say? MpG is down a good 5 to 7 mpg on average and i got screwed by a saxo. Not so good.
To be fair i can feel what it does, rather than your car having to wind up to the power kicking in it feels as though the engine is already ready. You don't get the surge anymore when the foot goes down, just a smooth gradual increase in torque.
However it makes my car feel as though the mixture is just too rich, i'm sure its actually slower and it just doesn't run as nicely as it did.
Needless to say changing it back to standard this afternoon!
I won't say which one it was as i am going to email the guy to ask if i have missed something when setting it up, give him the benefit of the doubt you know. Mind you although this one said for PB engine with Bosch management. I don't think i have a bosch ecu. maybe thats it.....
And my tyre popped, and my telly broke, and my dvd player broke. Yesterday was a crap day!
