Yes, i am still considering that for the last exit, thanks for helping sir,

Boom like I'm driving over 2ft lincon logs at 50mph.. 1 series.. As reliable as you expect

Hi, thankyou, yes, clogged injector which is that part?

Or is there something upfield before the cylinders like a throttle actuator that is controlling half of the cylinders? I am betting not but anything upstream that would effect those 3 cylinders My bet is on the 0xygen sensors which would explain it happening after the downpipe install. Get new sensors and put stock pipes on and it will go away

i'm getting your point here, so you think the oxygen sensor is the one that creates the problem? so i cannot use my catless downpipe, will a tune fix this problem

Ive replaced multiple knock sensors (4) on the n54T 1Ms. And Ive personally fitted an akra with downpipes and shouldn't be unrelated, if installation is correct and tune is right that is. Recommend evolve 3 tune by the way. Also check injectors!

nice, i'm starting to get sense of all of these, so guys, do you think it is possible for me to get a new tune and fix this?
WILL NEW TUNE FIX THIS?, just now i went to the workshop to start the car and nothing happen, when for a hard drive about 7 kilo and had a blast with the akra... so i guess nothing happen and the car adjust with it. but infact i turn off and restart the car, bang.. there it goes the shake.. a friend of mine said its the tune..
