I'm thinking of joining the BPU club whilst my supra is out of use because of the bad weather..... when I was modifying my old mondeo (different league I know ) I did all the normal stuff like exhaust, induction etc, but it ran pretty poorly until I had it unichiped and remapped, because the stock management didn't know how to handle it.
My question is, if I were to decatt, FCD, spark plugs etc, all the normal BPU stuff up to 1.2bar, will some sort of remap be needed to make it drive smoothly or will the stock mangement cope fine?
Cheers guys / girls
