i want to improve my cars performance, its only a 1.8 4cyl so not the quickest, i think its 115bhp.
it goes ok but i would like a bit better performance, ive changed to a green filter which has given me better throttle response.
can i replace the throttle body on my car with that of a 325ti compact throttle body?? would that give me more power??
ive thought about re-mapping but not sure it'll make much difference! anyone got experience of remapping on a small n/a engine??
any other suggestions??
im not changing the engine or turbo charging because these options are too expensive and not practical!
