I have recently changed from a 2000 318 ci 1.9 to a 320 ci 2.2 and it slower !!!! I'm considering having it chipped or re-mapped to increase the performance. Does anyone know where in the North West is the best place to get it done ?

  hello first time on the sight, in my expierience chipping 320 doesnt help that much, to be honest to 4 pot is best left, good news is that there a some good chipping kits for the 6pot 325s. not much help i know.

Hello to all

An atmosferic engine can be chipped but it will give you only arround 6 HP more. For Chipping are
only the turbo engines. There u can get with a chip some more HP out from the engine.

I would say that if you get yourself a professional exhaust system than u can get some 20 HP more.
But not with an chip. And also by polishing the inlet manifold you can gain some 5 HP more.
The atmosferic engine will get more HP only with seriouse mechanical operations. Buying and install a chip is throwing away money.
Trust me on this one.
