if i decat my seicento will it make a lot off differnts to power? what about petrol and noise? thanks

depends on the rest of the exhaust system

its only a backbox on it

no then, need to change whole exhaust including headers

TBO I have a decat and the effects really aren't worth the amount of effort it took, there are other things you could do that make more difference first

Bigger TB
Headporting
Cat back exhaust
1242 Conversion
75 Cam
GSR Induction kit
Remap or a Mckrich chip
New Manifold
etc etc

And if you actually do a turbo then the first 5 will work with that too

were do you get ur chip from and how much? cheers
