Got mine cut out on monday, didnt like it at 1st, thought it sounded too 'tinny' but the more i drive it the better its beginning to sound, popping and crackling at will changing gears/letting off the throttle.
My flat spot is between 2500-3000 and its pretty bad, my 64mm throttle body has seemed to ease it a bit though, my 197 is booked in to get mapped in the next few weeks and a map apparently gets rid of the flat spot so time will tell i guess..
