S1 BHP Upgrade Advice
I am running a totally standard S1 I don't want to mod it to much as it is too nice a car to be mucked about with, But I have seen a lot written about -31 actuators and chips could someone give me a rough idea as to what they would do to my car?
Do you just get a chipped ECU and off you go, Or is there more to it same for the actuator do I just buy a -31 and fit it? And whats the deal with the colour coding on the ECU?
I dont want monster BHP just alittle extra that I presume is easy to gain without major internal work.
Really need a bit of help and advice from some kind soul.
Thanks in advance
