Hi Guys,

Wondering if anyone can point me in the right direction. I have recently installed a 304 Rica into my 1997 850 t5, it goes like an M3 but unfortunately its developed a judder/hesitation at Wide Open Throttle. Ive read that its possibly misfire but recently sometimes i have a problem getting into second and third so im wondering if its clutch slip?

Any ideas would be greatly appreciated

Thanks,

Will,
