please excuse me if this is in the wrong section, 1st time post.
i have a 2010 e92 m3 dct which has an akrapovic exhaust and a dry carbon a/m induction.
the car has had an ongoing issue with misfiring under load (same hot or cold) and just wondering is anyone can give me any help as to what it could be.
i have sent it to my local BMW dealer numerous times and they have tried numerous things, none of which have fixed the problem and they are stumped.
the computer is not throwing any fault codes and if anything it feels like it is running lean or pinging, i have always used 98 octane fuel.
i have tried swapping the air induction to standard, BMW have done a software update, new spark plugs, new idle control module, temperature sensor.
someone said it could be the exhaust due to the lack of back pressure?
the car is fitted with a delete/r which stops the engine light coming on for the exhaust, bmw have also disconnected this system and driven it to see if any other faults come up other than the exhaust and nothing shows?
i love the car but its driving me insane can anyone help??
